Photography

You could remove "photo" from your question and it would still stand.

In almost any place where people gather - virtually or in real life - it is close enough to a certainty that at some point, however well-intentioned, well-moderated and well-meaning the place is, people will start being a**holes to each other.

I can think of exactly one place where this didn't happen, and that was on Ming Thein's site when it was running. The comments section of his articles (which was the closest thing the site had to a forum) was for the most part extremely cordial, or at least polite and respectful. Trolls and other such types were rare in the extreme. I can only guess that people were responding to talent and good writing.

But as a rule, yeah. It's like that old joke: God gave man religion, and then Satan came along and organised it. In this case it's like Tim Berners-Lee and the US military gave us the internet / web, and then people took this world-changing technology and used it to belittle each other over petty nonsense that means nothing.

Anyway, everyone knows that Canon cameras are garbage, I'm sorry, I said what I said, GTFOH, etc :-)
