you're right, this is a forum... and if you post an opinion, you assume the risk that someone will respond to your post/opnion. and if that post/opinion is factually impossible or unfeasible, you will likely hear a response from someone who lives in reality.
if you disagree with that concept, maybe an internet forum is not the place for you. you'd probably be better served having a conversation with yourself in the mirror if you don't want to hear a differing opinion, especially one that calls out the foolishness of your opinion.
