I've noticed that most MR issues are rather similar to issues faced by black men. That being said, MRAs are 99.99% SAWCSMs so is it appropriation? MRAs steal issues that affect black men and distort them by saying they only affect white males.
Some examples are:
Black men face more prison time for the same crime.
Black men are portrayed as rapists in the media.
Black men are the most afflicted with poverty.
Men's Rights Activists seem to replace black with white for these issues in an attempt to steal support from real issues.
