Actually, while we can't say anything about the merits of the complaint, it's obvious that Fox uses women as sex toys for the visual pleasure of its aging male audience. The women on the shows look really good, and they are revealing in their attire, clearly in an effort to boost the audience of the programs.
This is a station that constantly pushes for war against other countries and tries to convince its aging audience that locking up an entire generation of whippersnappers for smoking a plant is a way to promote the philosophy and practices of Jesus. While I'm no Christian, I fail to see what militarism and the War on Drugs have to do with the teachings of Jesus. Bernie Sanders behaves much more like a Christian than the allegedly prurient cretin O'Reilly.
Frankly, while I'm lifting weights in my community gym I'm sick of seeing this disgusting prune preaching to me why we must devote billions of dollars to fighting a war against cannabis (I do not smoke it, by the way, but I think adults should have a right to if they choose, since this is supposed to be a free country). Rush Limbaugh, a fellow traveler of his, was exposed as an opioid addict a while ago, but last I heard he hasn't changed his views about marijuana. Meanwhile, thousands of Americans are suffering or dying because they are denied access to medicinal marijuana, or are instead being pumped with pharmaceutical concoctions with risks that Big Pharma -- undoubtedly sponsoring these jerks -- downplays.
O'Reilly's shady background is well-known on the internet and is on his Wikipedia page, so we won't go into detail about it here.
I hope Tantaros succeeds in her suit and bankrupts Fox. However, a much more likely scenario is that Fox will settle to try to brush this embarrassing problem under the rug.
Here is a pretty good analysis of the situation from the Young Turks:
