I like what Wonderist says here. Try to be yourself if possible. Coming here to rant will help you vent that pent up anger you have. That's why this site is so important.
No, I find no happy median. I'm in a situation due to my hobbies (sewing and embroidery). I belong to several Facebook groups and, for the most part, the people there are very nice and I've learned to ignore much of the religious embroidery crap that's there and their requests that we "pray" that their design fits, etc. But there are times when I just want to explode. I was kicked off of one site run by a woman who lets everyone know how religious she is, for pointing out to her that she called someone "needy" and it hurt that person's feelings. I've not been here for a while, mostly because all I would do is rant but maybe, from time to time, that's what I need to do. Fortunately for me, my grandchildren are not being raised to believe in the invisible guy in the sky but I was guilty of providing evidence for Santa for too long. I do have a bit of fun by sending Christmas cards with Santa to the true believers. And don't get me started on tRump! I think I've shaved off years of my life in this past year.
I replied to someone earlier today on a similar topic. I told him that we Atheists have a responsibility to dismantle the stigma that the label Atheist holds that has been given to us by religious nuts. We must show ourselves as good humans, not perfect humans. We need to be respectful at all times even if we're upset. We are not perfect, but if we try to be as close as we can to being perfect, we will find that we will get closer all the time but NEVER reaching perfection. We are human so we make mistakes, but making many mistakes sometimes leads to success especially if you learn from your mistakes. I also said that you often may NOT get through to the one your aiming your efforts of sharing reason with, but more likely a bystander may pick up on your reason and change their mind. This is very true when the exchange is online where everything we do is recorded for anyone who wants to read it. I am NOT saying don't get upset. I AM saying be respectful at all times. That's not as hard as it sounds.
