A lot of what I see is also some form of redirected misogyny. Feminine qualities in a homosexual man is seen as somehow shameful. The flamboyant lisp-ing queen with a limp wrist who goes ," GURRRL..." quite frequently and owns an extensive collection of rainbow accessories, amongst personal traits.
While I think this stereotype is often overused, I think that to hate a person who so happens to exhibit these qualities naturally is... wrong. Some people are "that gay". So what? It hurts no one. it makes no one less masculine.
On the Flip side, gay masculinity has also been given this harsh stereotyping, as guys who have so much testosterone, merely being in proximity will cause one's 5 o'clock shadow to come in early; Leather, jockstraps, muscles, hairiness, etc. Bears are a mainstream cultural phenomena, and the rest of the world has adapted (Homo Sapiens really do like to maintain their munitions of stereotypes, and will create a new one if their previous one is debunked, or has fallen out of vogue).
Then there's Sex itself (and please don't take this as some anti-anal wackjobbery; whatever floats one's boat, after all); we have been stereotyped as a people who's only means of experiencing intimacy if via anal sex, which we self perpetuate in our erotic entertainment (porn) because we've been taught by straight people that it is what we're supposed to do, even though they hate us for it. I myself don't like "topping" or "bottoming" (not a "g0y", though; that's another can of worms). But that would make it harder for the homophobes to identify us as walking sex acts.
I have an observation (which some may agree with) in that homophobic straight persons condensed all these features into one or two "icons". They use it to target us, identify us for either attack or use (as in they use us like equipment/tools, rather than human beings). In the case of the latter, if we do not fall into their narrow categorization of homosexual, we are considered "useless". They only want to tolerate us enough to make use of us; to decorate their houses; to cater their events; to push them at the gym for peak muscularity; in other words, to make THEM look good. Most of straight culture thinks we control media aesthetics, but it's actually them that controls our view of who we are and who we should be, even if it comes from a place of discrimination, no matter how passive.
tl;dr: people who so happen to be stereotypes are humans too; all expressions of gender are needed, we hate each other because of homophobic straight people's influence, and merely tolerating us for utilization is not enough if we want to be viewed as equal.
bonus: bisexuals exist. don't shame them.
