So… make an echochamber and have everyone circlejerk each other…

Look while it sounds bad, you really cant have many worthwhile discussions if you only talk to the people you agree with, (ie. Like minded individuals) you need to talk to people that dont agree with you and that means that is very likely they dont think like you and things like sarcasm can go over their heads and think you are being genuine while you are not. So i say stick wit the " /s" thing
