I would like to recap with this:
It's cool to dislike something. However, that does not make it a joke, or "not music" (in this case).
Art is subjective. The things that evoke emotions and reactions from one human being are nor necessarily what do it for another one. That is the great thing about music; you have many different styles for many different tastes.
I love bands like Sunn O))), ISIS, The Ocean, Electric Wizard, for example etc...AND I'm not a huge fan of country music.
However, I would not call country music a joke, or ridiculous, because I know that for some people, that's the kind of thing that moves them.
I would expect this same courtesy from the people who are the other way around, and dislike the bands I mentioned.

Now, on to the Cthulhu worship.
