This. This so much.
Boyfriend is Christian and has expressed that if his grandmother (who is rather sick and in the care of his aunt) really wanted him to be baptized he wouldn't have a problem with it, and I asked if I would be welcome to attend that event. Unsure of how the church would feel about me attending, and he assured me that he would make sure I was there if I wanted to be.
I would always want to be part of something important like that to him and his family. I can enjoy the company of others, and offer my support even if that's something I don't practice or believe for myself. I've come to realize that an assumption has developed (even among other atheists) that because I don't believe in god it means I must hate religion and those who follow it, because of this generalization someone who may not know me might assume right off the bat I would have some ill will towards them and will immediately go into the defense.
I really want to know who decided to throw around these rumors and assumptions :/ because I am really tired of people going right into the comment of "Oh you hate Christians?" when they find out I am atheist. It's like a never ending 'blond joke' that I can't get a word in edgewise. Really it can become incredibly tiring..
I've run into a few atheists online who really are like this. They publicly and vociferously trash any mention of religion or beliefs that aren't their own. It is almost like they can't settle for having a different opinion than someone else. They have to be the most anti-religious person EVAH. With bells on! (but not church bells, because that would just be wrong ).
Maybe we could get the never-ending 'atheist blonde' jokers together with the never-ending 'religious blonde' jokers and watch their brains overload.
DH's college roommate and for a while best friend was like that. Every single chance he got he'd spew really hateful things about how religious people are stupid and every person of every faith in existence was completely wrong and how teaching religion to children ought to be considered child abuse. DH and I are both religious people, and these repeated statements were very hurtful to us both.
Like the OP, we were extremely tired of his trying to convert us. Unlike the OP, no amount of politeness worked in our favor at all. Eventually we had to just tell him what was wrong in the most simple terms available. When we explained that he was being very hurtful to us, he ignored our requests for him to stop. He tried to claim that poking fun at someone's faith isn't insulting. (On what planet, I ask.) We had to block all connections with him, online and off, for it to sink in that maybe we really meant it when we said that he had been cruel. Though I don't actually think he understood that much, since he later stole his girlfriend's email password to send more insulting messages, this time claiming we're committing horrible censorship for not listening to him speak his mind. :c
Some people just don't comprehend when the statements they make are hurtful to others. They're not going to understand unless told directly and without any room to mentally maneuver out of seeing their own actions as unkind. If they're convinced completely of how right they are, on whatever the topic may be, no amount of explaining will change their mind or let them see the cruelty of their own actions.
OP, I'm not suggesting that you have a heart-to-heart with this person over how they're hurting you with their pressure. Just know that it's totally okay to just zone on out and ignore any discussion of religion. You don't have to engage a person who is completely set in their belief on that topic.
