Personally, I ride in the rain because of the simple fact that... I like riding in the rain.
If others don't like riding in the rain, so be it, they're not any less of a rider, likely have more skill than I do? It's kinda like telling a guy he's not a man for having the heat turned on in his car during the winter. Another odd quirk, I actually like riding in traffic too, I see it as a challenge, to get from point A to point B in the same time as usual, but with heavy traffic, not unlike the rain, controlling the throttle so the rear tire slips a bit, but not too much, etc ...
TLDR; This is a pointless argument.
