Me being "well known" in general is news to me. However, the people I am that way are usually people like yourself. I am argumentative with people like yourself, however I try not to be "rude" but I am not always "nice". I think this is probably a cultural distinction where I make a distinction between Niceness and Politeness. Rudeness is the not-being-polite, rather than not-being-nice.

As for my "highly opinionated" things, honestly, I don't think I am that opinionated about many things, but I guess the ones I am on, they are the "well known" aspects. If I am wrong about something, I will gladly change my opinion given a good argument or set of facts.
