One point that hasn't been raised in this discussion yet:
When people ask a question or provide an answer with statistics to back it up, this doesn't necessarily mean it is their personal belief.
When someone asks a question like: "Can a cow jump over the moon".
If that is a common belief held by other people, some people insist on being a dick in the comments with suggestions like:
"What the hell are you talking about, you are a moron, cows can't jump, you tool!"
Just because you are asking about it, or just because you are quoting someone else doesn't mean you believe it yourself. Even if I want to find out the truth behind some claim doesn't mean I initially believe that claim.
Don't make the assumption or feel justified in attacking someone just because they asked about a claim that is made by others.
