So, let's talk about the phenomenon of not liking men so much.
1) Is it a real phenomenon? Yes.
2) Does not liking men/hating men hold the impact that not liking/hating women holds?
That depends. Generally, the answer is no because of massive power imbalances which exist across the (cis) male/(cis) female divide but there are exceptions in other contexts. Intersectionality complicates things. Misgendering complicates things. Patriarchy complicates things.
