Are you saying “stereotypes” are not based in FACT?
Some are; some aren't. And even when you can find true examples, it's people playing "god" who think their assigning of those stereotypes sweepingly across the board that's part of the problem.
If people oppose Obama's policies, it doesn't make them anti-black...though I'm sure many racists are anti-Obama. But for someone to try to presume that the reason someone inwardly opposes Obama's policies is his skin color has just bought into an MSM stereotype.
If people oppose Pelosi's policies, it doesn't make them anti-feminism...although I'm sure many traditionalists are anti-Pelosi. But for someone to try to presume that the reason someone inwardly opposes Pelosi's policies are her sex would buy into a NOW stereotypical soundbite.
If people oppose Mormon theology, it doesn't make them anti-Mormon...just because people on one side try to "air out" beliefs (which are in fact deceptive) and people on the opposing side of those beliefs likewise try to "air them out" for people to see what's off-base about them...doesn't mean that your stereotypes automatically apply to anybody you want to hurl them at.
