I can't speak for Americans but where I'm from, actual assault or rape on a woman has always been taken seriously, at least as long as I've been alive. Nothing much has changed in this regard.
Metoo tried to push the agenda that if a woman sleeps with a movie producer willingly for a promise of a movie role, if that role falls through, she can change her mind and decide it was rape months later. That's absurd but hey, it's nearly impossible to prove unless you have witnesses. To me it just looks like sex is just a currency in Hollywood.
Women have been using rape/abuse accusations to achieve things for a long time, not all but more than a few. Amber Heard isn't a very rare case, there's plenty more just like her. It's done because it works so well. If we didn't have recordings on the Depp/Heard case, Depp would likely be in jail now. Makes you wonder how many innocent men were locked up before smartphones became ubiquitous.
To me, racism is still alive and well and it's most prevalent among blacks. There's so many ridiculous claims and cries of racism that the word itself has become a meme. You'll see black people aggressively confronting random whites for "cultural appropriation", violently assaulting Asians, using more racist slurs than any other race and doing it openly. So for me, when I hear claims of "racism" by black people, my first reaction is that of laughter, the word has been overused to the point of not having any power.
