If it's someone on another forum, why do you give a crap? Do you know them in person? If not, why care about their opinion?
I don't mean to sound harsh, but I reserve the people who's opinions matter to me to those I know well (and generally like) and people of some importance. Some Joe Schmoe off the net matters little to me. And you shouldn't get too worked up over it either. Enjoy what you like and let them waste time getting all bothered about it on the net. There's too much to enjoy out there in life to give it any worry.
