Malice Mizer (the user, not the band), moderate your words. There's no need to swear to convey your message.
You can't expect everyone to share your tastes in music (I know for sure that few listens the same music I do), and cannot as well expect them to know what are the main features of this band, and jrock in general. Personally, I don't know anything about them, they could be as well horrible or awesome, but you have to admit that they have a rather femal-ish look, and the ordinary man doesn't know that "90% of Japanese rock bands wears in strange clothes" as you said. Therefore, the ordinary man's first reaction
is "Hey, they look perfectly gay!", which is quite a normal reaction, if you think about it. You should first try to provide some further informations and what their message is, and then eventually complain about the dumbness of whom hasn't understood your explanation. After all, you never said they
aren't gay. And "gay" is not always to be intended as an insult. Sometimes it is, but not always. So, try to be more clear (and patient) before jumping to swears.
I promise I'll inform myself about this band, since you (and taikara, whose tastes are good) say they're good, I can't say they're bad before checking
Btw, thank you for helping us improve the word filter (c*nt wasn't being covered, and since this is a PG13 forum we got to control coarse language).
