I know what you mean. I've often posted things with the instinctive knowledge in the back of my mind that it's best left unsaid, but the urge was too powerful to resist and I also just hoped nobody would get offended.I prefer logic to emotions but it has bit me in the behind more than once. I'm going on an autistic tangent but: if I think there's no rational reason for someone to get upset I will post what I think even if somewhere in the back of my mind I think maybe someone might get upset. I've had to tweak my decision making to be more intuitive than rational as that seems to be the dominant way people react, even in the autistic community. Which is a shame for me personally as I get frustrated at things that go unsaid.
It's like when I saw a political thread that I had a very strong opinion about, and being so it was a discussion thread I thought there'd be no harm in throwing in my view or experience. But, alas, there was. Whoops.
Then the next time I gave in to impulse, I thought "I'm not going to post anything...ohhh what the hell, I have to let this out!" *Tap, tap, tap away at the keyboard, doesn't proofread, submits, gets on with whatever I was doing before I checked the site, come back to it a bit later, suddenly finds out I have made enemies and the whole thread has become a flame war*
Rinse and repeat, except my intentions were always down to impulse and obsessing over political matters, not to sit and laugh at people getting offended and having no remorse or guilt.
