I will give some examples and hopefully you can see where I am coming from

Black people:

Black men are portrayed as hypersexual predatory and violent beasts who cannot control their urges to themselves and always take out their anger on innocent folks such as women and children

While there is some running stereotypes of course black women being arrogant, cold-hearted, loud and brass, when it comes to the media portrayals there is no doubt black men get hit with a stronger stereotype profile

Muslims & Arabs:

The obvious one, Muslim and Arab men being terrorists or terrorist-sympathizers, jihadists and then a more obscure one that al Arab & Muslim men are wife-beaters and goat torturers

LGBT:

How bout the classic hypersexualized gay male dude-bro who's apparently always sexually harassing other men or the so called groomer panic from tradcons?[What's funny to me is they always move on to another male target, remember when they did it with Muslims and Arabs]? also, can't forget the stereotypical male creep playing dress-up pretending to be allegedly MTF

Hispanics[particularly Mexicans]:

How bout the running trope of Mexican and Central American men being violent predators who all illegally came swimming through the Gulf of Mexico who target women and minors? you especially see this a lot in anti-trafficking circlejerks

Autistic people:

Autistic men are far more likely to be creep or incel-shamed than their female counterparts, there is also a running stereotype of autistic men being hostile misogynists

White people of Eastern-European origin & slavs:

Russian men also are constantly hit with the stereotype of being wife beaters, deadbeats and at-home alcoholics during family in-stays

Incels:

This is probably that one you were hoping for, but is true that not all incels want to go out of there way to sexually assault women or are planning to be domestic terrorists or are even partaking in extreme red-pill/black-pill content, in fact most womanizers are literal chads and alphas themselves, similarly whenever there is a racial hate crime committed people immediately jump to body shaming conclusions and assume said white supremacist couldn't get a date or had off-putting looks, but would you consider Dylan Roof for example a guy with sub-par looks?

Have I provided enough examples? I believe I have, but let me know if there is more that I can think of
