If someone chooses to like something or do something because others dislike it or choose not to do it, the fact of their choosing is compatible with them liking it for additional reasons. And that's uninteresting too.

I just don't get why the "pro-skub-anti-skub" dynamic exists at all.

"I like to ride bicycles because others do not, and because they're convenient" is simple, and moreover, it need no social anxiety to attach itself to the shorthand, "cyclist". It seems as of late every social category that crops up exists solely to spark this type of "definition sharing" talk exchange.
