I think your arguments are a little disingenuous, to put it mildly.
1. You compare an adult person selling nude photos of themselves to somebody attending a white supremacist rally....
Surely you can see the difference here?
One is perhaps amoral, by traditional Christian/religious values, but not illegal - just like blasphemy or swearing is no longer illegal in most parts of the world. And religious points aside, an adult selling photos of themselves without clothes on doesn't hurt anybody.
White supremacy on the other hand is closely entwined with racial discrimination - which is illegal, and does hurt people.
2. You say that it could negatively impact coworkers performance, as it might distract them.
Assuming that the videos are made on personal time, and not during work hours or during work time - I fail to see how this is the person's fault.
This is victim blaming - which is a terrible thing.
It's like saying a girl is "asking for it" based on the clothing she wears (which people have used in parts of the world to justify rape) - except in this case, it's what she wears at home, away from you.
3. Sexual harassment
I'm not going to weigh in here - this is a seriously nuanced topic with a lot of emotional content that can trigger people, and I'd make a mess of it.
All this being said - I always find it funny how Americans seem perfectly fine with insane amounts of bloody, gore and violence in television, film and games - but any hint of sexual impropriety or nudity immediately triggers them.
Oh, you can to show somebody getting decapitated, or having their fingernails torn off? Sure, that's fine, that's a normal action film.
Aha, you want to show a nude man from the front? Nope, can't do that. Oh, you want to show a woman's cleavage? Err, you're not going to get a M rating.
From what I've seen, the Europeans don't seem to have the same hangups about nudity or the human form.
I'm not a historian - but I wonder if perhaps it's the American Protestant heritage?
