Gaffa, I'll try to explain to you in form of an analogy.
Imagine you'd be a regular reader of a movie forum. People there like to watch French movies only. It's a community of people with similar interests: French Movies. They aren't interested in hearing about other movies - after all they frequent the board to share knowledge and interest in French movies.
So, one of the regulars goes to a French movie and finds out that it is not worth it. Actually, it's one of the worst movies he has ever seen, and it was an utter waste of time. So, he writes a posting on the board, telling his friends that they shouldn't watch this movie, since it's most likely no fun anyway.
Well, what do you do? With the same behaviour as you have shown here, I'd expect you to jump in and explain to the regulars, that it's absolutely ridiculous to jump on a movie. After all, it's not forbidden to watch a movie like that.
You understand now?
