I've been working with my therapist on this, but I still can't make the connection.
Religion has been responsible for the bullying of gays leading to suicides, the justification to limit progress, keep blacks segregated and enslaved, and often makes people cruel to one another using them not living Biblical lifestyles as the excuse.
Religion has not been responsible for these things,
people have been responsible for these things and have used religion as a justification. It's not much different from the people who do stuff like say something rude, then say "sorry, Asperger's," without trying to learn to not be a jerk, as though having Asperger's is a "get out of jail free" card for social tact (or lack thereof).
Let's look at this logically:
1. Person A is a relentless bully. He is also atheist.
2. Person B is also an atheist.
3. Is Person B a bully?
Going by the logic that you're using to justify your behavior regarding religion and those who are theist, then yes, Person B is a bully. That's faulty logic, though, because being an atheist does not have any bearing on how an individual chooses to act. Person B is no more or less likely to be a bully, just because Person A is and they share a philosophical viewpoint.
Also, why is it taken personally to make fun of a particular belief? That isn't calling the person who believes it names or discriminating against them. It is just saying that the belief is a lot to swallow and seems to be rather silly and unfounded. If someone believed there were floating tea cups in space or unicorns flying around somewhere, wouldn't most people laugh at that?
Making fun of anyone for anything is unacceptable behavior. You made fun of
people, when you wrote this line:
Try to imagine it from a perspective of someone who walks around being surrounded by people living under a delusion that they have to try and personalize the universe and nature all the time.
People took it personally, because you said that theists "live under a delusion." In effect, you called a number of people "delusional." That is very much a personal attack. There is a difference between saying, "I didn't agree with the tenets of the church I grew up in, and don't believe in god," and saying "people who believe in god are delusional."
Regardless, though, there is a time and place for venting your frustrations about religion in general, and engaging in debate over the merits of certain religious texts.
This thread, however, is not the place for it.
