Men are overrepresented in high risk occupations and historically men were expected to protect the family from danger so MRAs basically use this to "prove" that men actually the real ones experience sexism. However they won't go beyond this surface level analysis because then you would have to question the existence of these social structures and possibly get rid of them which would mean they can't play the oppression card anymore.

You never see MRAs advocating for safer workplaces or tearing down regressive gender roles. It's always "women should be grateful and should shut up because men are the ones who are actually hurting"
