Well if you're correct (which English sources seem to back up) then both I and a female friend of mine misunderstood that intention. When looking it up the German Wikipedia (since the source we saw was German) says that all murders targeting women can be included in the term. I'm guessing that it was just badly translated from English to German and then I made the mistake translating it back the same way.

The ideal solution then would be to properly call out the problem (hate crimes not being recognized as such/being properly punished) rather than trying to target a specific kind (though it was in a feminist context so it is sort of fair).

Also as far as I know killing somebody would just be a life sentence as long as it was planned anyway so it probably wouldn't be relevant anyway.

I'm going to guess that your last paragraph was a joke because there are actually some nice men that I know but basic human decency does seem a lot more common among everybody else.
