Sorry, not trying to be a jerk. But like Nanila, I am a scientist. I try hard to ensure that the information I present is as factually based as I can make it. I do this, in part, because I'll feel really bad if I provide misinformation. So when I present a fact and the response is "I disagree", which is really ONLY interpretable as "I think you're incorrect", it's possible I might get a bit snarky.

I'm happy to be challenged on statements if you think I'm wrong (and I certainly have been known to be). If you had asked for a source or something to back up my statement, I would have been happy to provide it. And, in that case, if I'm snippy with you for simply asking for more information, you would certainly be right to call me out on it.

Anyway, not that I think anyone has to be particularly concerned with that, as I'm not much of a commenter. This is probably about my 10th lifetime comment on the internet.
