You aren't wrong about many of the things that men face. The problem is, they are all caused by patriarchy - a social system that most men are fighting tooth and nail to keep from slipping away. If women are sick of that, it's not like you can really blame them.
The "manosphere" is made up almost entirely of middle class white men who are having a cow that their unearned spots as the default citizens are going the way of the dinosaur - and they are outraged about that and "fighting back" - by pouring poison into the ears of any man who is even a little bit vulnerable to the message that it's all women's fault.
As I recalll, Lorena Bobbit has been systematically abused for many years - including being raped repeatedly by her husband, before she finally cut off his penis. I don't think that is something anyone should laugh about, but I also see why some women might since nearly all women have suffered at least some forms of sexual abuse - a state of affairs that largely goes unchecked in this culture -and at least one man finally had a serious repercussion for that. But somehow that never seems to enter the equation when talking about empathy for men - the ways that all men contribute to that culture by turning a blind eye to it, disbelieving survivors, letting perpetrators off with a slap of the wrist, not challenging rape culture jokes, etc., etc., etc. Where is the empathy for women?
I'm sorry, but "this society existed like this before I was born" is not an excuse. Are you content with the level of racism in this country and expect that white people bear no responsibility for continuing to make it better just because the culture was already racist before they were born?
Acting like somehow women are just mean and shitty for ABSOLUTELY NO REASON WHATSOEVER is just completely tone deaf. Don't get me wrong, I'd love to see a culture that is kinder, more compassionate, and freer for absolutely everyone, but until men start taking a bigger stake in making that happen, particularly as relates to women, being upset that they have had enough is asking too much.
