None of these things are particularly nice. Some opinions, though okay to have them, are better unsaid. In this situation, I don't think you shouldn't think what you think about VGDJ--but rather, if it sounds like something that may potentially piss someone off, it's probably better that you keep that to yourself. Not only do you spare that person's feelings, but you avoid dealing with the drama that is caused by that initial wayward statement. And getting personal with people is never a good idea either. To your defense, I wouldn't've replied as argumentatively as jill and steve did, but nonetheless I wouldn't've been happy to hear that either.
And yes, I know it's the internet, and people say that you shouldn't take the internet seriously, and I agree with that as well. But it's not an excuse to be mean ;D
