Yes, I do think that modern feminism has a big component of man hating, and that's a pity, given the great tradition of sane feminism quite some years ago.
If you cannot see how putting a "man" label over some negative behavior is sexist, I don't know what can save from all this internalized mysandry.
Maybe you should try and change your point of view: female have mood swings much more often than men. It's biological, happens once per months, more or less. Should we call this "femm-whining" or "woman-swings"? Female cry much more than men, should we call this "femm-crying"?
That would be as sexist as "manspreading". I believe any decent person should avoid these sexist slurs altogether.
