Every once in a while a man wins in a court case like this.

But courts will rule against you any way they can. Example, if a woman keeps a written log of what her boss does and says that's evidence of a "pattern" then he's automatically guilty, if a man keeps the log they'll say it's just fiction made up after the fact and throw it out or a jury will just ignore it.

So you need to collect the best evidence you can and then you'll only win the most egregious of case, but you can win. But if they cartoon villain say "I fired him only because he's a man and I'm a man-hating lesbian" and it's just your recollection then you missed your chance.
