I neither know you nor your content, but let's presume that what you posted was percieved as an utter garbage position to have. Yeah, that's what downvotes are for.
But a ban? Those aren't for people whos opinions you disagree with. Those are for cleaning up after people who intentionally tris to stir up something.
Well, if it's against the rules, then it might justify a ban. I'm not going to argue against rules in general, and interpretations thereof.
