Morbidly A Beast:
I think there’s probably creeps who think fat people are vulnerable but then are btfo’d and sorely mistaken when they try their moves on people

Munchies:
I wish that it were that simple.

The fact of the matter is that a lot of fat women have internalized fatphobia. So, unfortunately, that can make some of them more vulnerable to manipulative, abusive people. They think this is the best it gets for them, so they end up tolerating things that they shouldn't have to tolerate.

That said, there are plenty of fat women who have enough self-respect to weed out most of these creeps. Sometimes the slyer creeps fly under the radar, so that will only get you so far.

Nok:
They are worse than human garbage, bordering on being truly evil. There are obligate predators, people like serial killers that are driven to do evil, but in the same way that I'm driven to eat chocolate or maybe someone with tourettes is driven to tick. As a society, we need to remove them, but their "evil" is overblown.

Then there are facultative predators and opportunists, people that do evil because they think it's fun and their bored or because it is moderately easier than something else (or, tbf, because they had it modelled for them by other people in their lives, friends, parents, etc.). People that intentionally cause pain and damage and are not "unwillingly" evil. Those people are truly among the worst humanity has to offer, imho, and I'd say the group you describe falls in that category.

Fatman76:
And that’s a problem why?

Fatman76:
Thank you for that is very good to know.
