Scientist, I was the first person to make a specific religious claim on this thread, so I'll weigh in. You said:
"I tried to make my point and I don’t want a fight over it. I just think that bringing things like religion (or politics) to a board like this alienates people. Saying “Happy Easter” is fine – it is the declarations of specific religious claims that seem like they don’t belong here."
I think that your point was pretty well understood- it's just that many of us don't agree with you. It does not seem that too many people were alienated by a traditional confessional statement on the holiest day of the year in the world's largest religion. Some of people agreed, and others were content to let it pass without comment. That's called tolerance, and it is a fundamental tenet of a free society. What alienates people is being told to sit down and shut up.
Your point is well-taken about how some comments would have been in poor taste. It's also in poor taste to expect people with specific religious beliefs to be silent about those beliefs in a thread dedicated to greeting each other on their holiest day. A thread, no less, started by the host of the website. It's not like a swarm of fundamentalists took over the site. Pavel posted a Happy Easter thread, and a few Christians (and others) responded with traditional religious greetings pertinent to Easter. If you had not felt compelled to play the role of thought police, this would have ended yesterday, and we'd all be talking about training right now.
Let me invite you to cultivate an open mind and good will toward your fellow man. You may find that it serves you well.
