Why can't we all just get along? (Details inside)

This question is inspired by this s*#$storm that was stirred up yesterday.
A person of Christian faith asked a question on a point of doctrine. Perdictibly, a couple atheists felt the need to jump in and nay say the entire business. This is unhelpful to the asker. We all know there are atheists. You don’t believe in God. We get it. The asker is not asking you for feedback. Telling the OP that what he believes is bullshit is not even moderately helpful.
You can yammer all day about how not allowing someone to have their delusions can only help a person. To that I wave the bullshit flag. The only thing an answer like this accomplishes is a sense of adversarialness. It’s all about “I’m smart and you’re stupid because you believe all that crap.”
I’ve seen the lame, wornout excuse over and over again; “Well, those darn Christians are always ramming their beliefs down my throat.” Again, I wave the bullshit flag. This is an internet page. Just words on a screen. Since I have been here I have seen no Christian claiming to be the only right one in the room and forcing a poor hapless atheist to say “Uncle”. Quite the opposite.
So, in the interest of peace and goodwill, and the enlightened tolerance that so many liberals claim to have, why not just allow people of the Chistian faith to answer questions about specific points of doctrine? Not general, “Does God exist?” questions, just the specific points that other people of the Christian faith can answer.
How ‘bout it people? We know what the atheists believe, we all know what the Christians believe. Can we refrain fromn starting an argument or belittling someone who does not believe the same way we do?
