I can't speak for the previous poster - but many people I know (including myself) take pride in being weird; after all, what is there to be proud of in simply being the same as everyone else? I doubt "weird" was meant as an insult - I certainly didn't get that tone from the previous poster.

The rudeness comment is in reference to your rather aggressive response to what I perceived as a bit of idle observation. He indicated that preference without rational reason is weird (and to be honest, I'm inclined to agree), and you responded by insinuating that he would blindly eat anything presented to him, which is clearly not the case.
