I haven't had a problem with Harley riders. Hell, the first "biker wave" I got, 10 minutes after getting my RT from the dealer, was from a batch of Harley riders. And I've had some good chats with them in the motorcycle area of the Washington State Ferries.
Gotten the occasional snarky comment from Gold Wing riders, but for the most part they've been okay as well. Had some real fun trading notes with a batch of Piaggo MP3 hyper scooter riders.
As for the "real man" thing, personally I could care less. I'm not operating my RT with my genitals, so I could care less what someone else thinks of my masculinity.
