I don't think it's that bad anymore, but there definitely was a time during the late 2010s where the man-hating got a bit too much in my opinion. Maybe I was just exposed to it more due being in an industry that attracts a lot of hyper idealistic people who are oddly comfortable being very antagonistic toward white men especially. According to my boyfriend, he hasn't really seen or experienced any of the behavior I was witnessing evolving over the years but he is also not really part of "my world" so to speak.
I think it very much depend on what environment you're in. Just like there has been a lot of focus on women harassed at their male dominated workplace. It's definitely real and they definitely have experienced that, but it doesn't mean it is a 100% universal experience. I personally haven't experienced harassment from men in the workplace, but there definitely are women out there who haven't been so lucky. It really comes down to what the work culture is and whether it is built on mutual respect or bully-like hierarchies. The latter is the type of work environment I will avoid like the plague until I die.
Anyway, I am sure that there are white men out there who feel antagonized at work, but it's not universal and it is most likely in very specific areas where the work culture adheres to the most extreme fringes of leftwing ideology. Could also be in the opposite of that if the white man doesn't live up to whatever they think makes a man a man in the extreme rightwing workplaces these days.
