I have to say, I also see this as a legitimate line of questioning.
To summarize the best point of the thread so far, IMHO, not all gay people are alike. The reason you notice some more than others is because some are more noticeable.
It’s easier for most people to pick out the gay people who conform more closely to the contemporary stereotype. Therefore, those are the ones you notice. They’re usually the ones who take a very vocal, active stance in defense of equal rights for homosexuals, and they do a great job of raising awareness of the gay population.
There are a large number of gay people who don’t conform to the stereotype. They’re harder to notice, and therefore tend to get a lot less time in the spotlight. As has been pointed out, what’s more dramatic; drag queens out partying, or two homebodies zoning out to Buffy the Vampire Slayer and eating Cheezits?
So the media tends to lump all gay people into the easily available stereotype, therefore making the story easier for consumers to digest. The fact that it’s misrepresenting the population as a whole, and confusing people as to the nature of gay life, is incidental. But the fact is, there are as many gay lifestyles as there are gay people. That’s just harder to get into a three-minute news blurb than “lookit them crazy gay people, at it again”.
Personally, I’ve never been comfortable in bars, don’t drink or do drugs, and never went through a really promiscuous phase. I’ve finally found a partner who I think is the most loveable human on the planet, and we’re working hard to build a loving, fun, and lasting relationship. It’s no better or worse than any other gay lifestyle, but it’s the lifestyle that makes us happy. Walking the dogs, doing the dishes together, watching movies, playing games with friends… it’s heaven.
The other thing to remember is that being outrageous, strange, bizarre, promiscuous, different, flamboyant, and/or contentious is not a crime. While I don’t choose the stereotypical gay lifestyle, I’m appalled that people tend to regard it with horror, as if being all those things makes discrimination against people legitimate. Sure, some gay people do things that some straight people find outrageous. So what? Just because we behave differently, it doesn’t mean that we deserve to be treated as anything less than equal.
Finally, imagine if you will that the only mental image you had of straight people was news clip footage from titty bars. How would you feel about straight people?
