It matters because you're being unnecessarily abusive for no other reason than to offend others. Calling people "gay" and claiming they sing out of their asses, and in the Simple Plan thread, SPC getting called a "skank". None of that shit is necessary.
What you're doing isn't merely sharing an opinion. Like I said, no need to be so heinously outspoken. We get the point. I think you all know pretty well what the consequences are for disregarding warnings.
Stay on topic, but the bash-fest is going to stop right now.
