I am... but not so much online. I don't see the point in arguing with a person that is miles away for most part. That, and the fact that some people just tend to stay anonymous and think they can get away with whatever they say. I guess one can see trolling as a way of "arguing" nowadays.
Don't get me wrong, there is nothing wrong with using a screen name (I mean, I'm using one right now), but I always felt that online arguing is so inherently different from having an actual argument with someone in real life.
I've found that arguments online often end up like the eye of the storm. I have an argument with someone and then people gather and pick sides. And before you know it, it's 50 people engaged in an all out verbal brawl. I have had a lot of these situations where no one knew who was referring to what since people kept smashing the reply button over and over before one could actually finish an actual defense that as well written. Also, I've found that people, even if they like to argue, or even choose to get engaged in said arguments, have pulled this "TL;DR" attitude (for the ones not familiar with internet lingo; Too Long, Didn't Read). I can come up with the most elaborate point of view, that might be totally spot on, but internet is, in my opinion a terrible medium for it. A lot of people wont even sit down to read a decent plea if you're arguing. They just discard an opinion because it's not interesting to them to spend time on, but will keep on arguing, even if you actually debunked their point of view multiple times in a single post. I will vouch for a clear and readable post. A post with no white spaces and just a wall of text does not invite to read. If you can pull up an argument with good spelling, grammar, if needed numbering or bullet points and enough white spaces to make it inviting, I wouldn't mind sitting through it. It seems that some people don't even understand that concept. To me it looks like if someone would be speaking to me and not taking a single breath blurting everything out at a fast pace.
In real life, however, you sit down, and listen to everyone (and preferably just a one on one conversation) let that sink in and form your own side of the story. There is pretty much no walking away. Well, there is, but that is considered rude. It's equally rude online, but there seems to be less etiquette about it. It feels that in real life you have this obligation to finish an argument, where online, people can log off, and just stop caring about it at all. While someone might get all riled up over a ****** argument, and someone just said it for the shock factor.
Similarly, I guess I avoid confrontation online a lot. There's no point to that. Online I'm more of a "let's agree to disagree" type of person. That works best. People can still say what they want and I might or might not bite. If I were to argue back and forth until I got my way I'd be going on for ages. By now I know that a lot of my personal ideologies wont get a lot of people to back me up. But as I said in a different thread here "popular opinion does not make it the right one". I'm fine with not marking my territory everywhere, heck... in a lot of cases I don't even care to be right, since it's a subject I know nothing nor care about at all. Some subjects just seem so mundane... and while I understand these are serious issues, I just can't get over the fact that these things persist to be topics that need to be discussed ad infinitum and still show relatively little progress with humanity.
In real life I can, and will be argumentative. Most likely that's the only verbal interaction people get out of me. Maybe it's the aspie brain that thinks some stuff doesn't make sense and where I have to question it. I'm not going to settle with "just because". Especially since I'm well aware that people rarely walk out from an argument in real life. It's probably also where I make other people feel awkward and question why they do what they do more.
What I can't stand is when people argue and exercise power because of a position they're in. It's the arguments I had with my dad, where it came down to "this is my opinion and if you don't like it, you can pack your bags and get out of my house". That's not an argument at all. That's just him getting off on having power over someone. And these kind of arguments exist within employment as well. I've had many issues with supervisors who had this same idea of how to finish an argument. Suffice to say, it's one of the reasons I had some issues with keeping jobs. In real life I wont have anyone piss over me (proverbially speaking) and mark their territory because they think they can do so (and like to do so). And I guess similarly, there's arguments with people who only hear what they want to hear and just don't listen at all.
That being all said; I don't have to pick the winning side. I pick the side I like most. I like to stick to my principles, even if some of my ideas might border on some kind of utter madness that goes against all reasoning (well, it doesn't go against my reasoning). If I like it, I will defend it.
Also on the note of arguing on- and offline. It's interesting how some people often say things online they don't say offline. I mean... really? If you wouldn't dare to say it out loud offline for chance of repercussions, why would you say this online? It's the fact there's no fear in being online like this, where people have an opinion on everything no matter how ill-informed they are. It's where people plea for "freedom of speech", while with the internet there's also a certain degree of "freedom to get educated and informed", yet the latter is easily waived. Yes, I can understand people don't have time to read every article and get informed about everything. But then just don't mix in with the discussion at hand and move on (or STFU, if you will)... there's a reason I stay absent from some topics discussed on this forum (aside from moderating duties).
