As portrayed in movies and TV programs, especially sitcoms, homosexuals demonstrate a "lifestyle". If you don't agree with it, complain to the movie and TV producers who are creating the stereotypes.
The media portray homosexuals as fun-loving, hip, non-judgemental, stylish, well-groomed, sensitive, everything positive, never negative. They don't show the bath houses, man/boy abuse relationships, bug chasers, effects of AIDS, or promiscuity.
Conservative people are stereotyped as narrow-minded, uneducated, out of touch with contemporary life, uncool, uptight, and hateful, with nothing positive going for them.
