it's not about "importance"; it's basic aspect of a conversation; if you're having a real conversation, that's what you do. discuss. converse. make points and counterpoints. agree or disagree. should be simple for anyone who made it into kindergarten.
now if you're just trolling, that's one thing. that said, you're inability to follow posts and discussions in a topic you created, and continue engage in, quote others and add your response, etc., is your problem, not mine.
perhaps if you paid more attention to the ongoing discussion vs making your talking points; or reading with comprehension, it would make more sense to you?
