As a minor aside, I would like to address this other comment:
...I don't necessarily find religion to be a bad thing, unless it's used to divide people, to deny science or to promote one's personal beliefs into the government.
Earlier though, this different
comment was expressed:
I have many wonderful Christian friends who never try to change me and I never try to change them.
Those are 2 conflicting sentiments though, with different implications. Suppose a Christian friend was not openly trying to change me, but that same Christian friend was also trying to promote their beliefs into the government. So it does meet that 3rd criteria above of religion being a "bad thing," but then according to the 2nd rule I still would never try to change them, because they are not trying to change me, at least in a very public and open manner (though they may be trying via more disguised means).
The intentions and motives are noble of wanting to help people, but this outdated, passive posture of "I only care about the beliefs of other people when they try to impose them on me" is very shortsighted and allows room for a lot of bad beliefs to impact us, just in a more under-the-radar fashion. It is a discussion we had extensively discussed in a different thread recently, and it will never evaporate like it needs to, but I feel compelled often to address it because that attitude just is not going to help us enough.
When people across the dinner table espouse bad beliefs and bad justifications for those beliefs, we need to be willing to criticize them at the outset. Not just wait until those beliefs potentially transform into laws and then we hold rallies to protest them, and often fail. Start criticizing the bad beliefs earlier, before they have even more time to germinate and spread.
Regarding the comment that you linked, did you miss the part where I said sometimes it was fun to argue? I've argued for fun many times, knowing full well that it's very doubtful that I'm going to change someone else's mind or opinion. If someone is honestly seeking, then it can be worth trying to convince them. If someone is obviously convinced that they are right, the only reason I might argue with them is for fun. Debating can be fun, even when you know neither side is going to change. There is always the small possibility that a person who is seeking for change might benefit from reading an argument between a Christian and an atheist. But, that's rare. I like to argue politics too, but so far, I've not convinced anyone that I'm right and they are wrong. Sometimes you just need to let someone know that there is another point of view. That is why I've never hidden my atheism, and have no problem standing up to Christians who are obnoxious.
All of my Christian friends are Democrats who support the separation of church and state. Even my mother, before she was overcome by dementia, strongly supported the SCS, and she is an evangelical. She and I had far more in common than we did differences.
All of my Christian friends know that I'm an atheist, and yet, they only judge me by my character, as it should be. I also see them as good people, who for some reason find strength, community etc. from their religions. Perhaps, some believe because that's what they were taught to believe, so their beliefs are maintained out of tradition and culture. So, I strongly disagree with your assumptions. I do have atheist friends who think like you do, and it's fine for friends to disagree and still be friends. So no. I am not going to judge my Christian friends or try to convince them they are wrong, unless they want to get into a discussion with me about why we have such different beliefs.
Believe me when I say that I have been confronted by the more unpleasant variety of Christian, the ones who judge me harshly, the ones with closed minds who think only they have found the truth. I have stood up to these people, but not one time have I ever been able to convince them that they are wrong. I only have one casual friend who is deeply brainwashed by her faith. We aren't very close but as we are both nurses ( I'm retired. She's still working ) we have a lot of respect for each other for the things that we do/have done for others. We never discuss religion or politics out of respect for each other. What would be the point? I'm not going to change her mind. Her mind is made up. It would only make her feel bad, and she already has so many problems in her life, it would be cruel for me to add one more. I'm not sure you understand why some people need religion.
And, since I don't believe in freewill, I realize that all of my Christian friends believe what they do because they have been influenced both genetically and environmentally to accept these things. It's possible that something might happen in their lives that will make them see things differently. For example, we had neighbor who was very religious. His young son died during a short illness. He immediately lost his faith and became an atheist. But, even tragedies like losing a child, aren't always enough to make a believer change. Some will use the excuse that it was god's will and we can't understand how god works. I think that's probably how 1I sees things.
If you are worried about those who want to change laws based on their religious beliefs, the best thing one can do is to become active in politics, run for office, get involved, help register people to vote, give money to people who will support your views, and above all else vote. Trying to convince individuals that they are wrong on an individual basis, in the hopes they might see things your way is pretty much a fool's errand, imo. Still, it can be fun to argue with those who attack us.
