Op, I want to ask you if you are lecturing bitcointalk community users on how to discuss or you want to learn how to discuss?
Hahaha.
His words are kinda confusing. The first line of the second paragraph explained exactly what he meant to say, about people having different opinions.
OP, Being able to accommodate and give users the opportunity to say what's on their mind is what this forum is all about. Every forum is all about discussion and same is this. For me, so far a post or comment is right in track, whatever contributions matters, nobody is shutting anyone up.
