And higher work-related accidents will happen when society has taught us that women should stay home and take care of their kids. It's changing but it's still more common for women to do this, and as such, this will lead to men having higher deaths in workplaces.

You are right about men getting screwed in family courts. And it's something worth discussing. However, I don't think this is "oppression", the law has issues in many ways and I think needs to be looked over in many respects. Everyone seems to get the short end of the stick in some way and this is unfortunately ours.
Understand that I don't think all of your issues are invalid, But I don't think this means white men are oppressed. I think we are seeing many issues that have always been there and just never have been addressed.
