The problem with the "men's rights" movement is not that men still don't face injustices--they are more likely to be the victims of violence, more likely to commit suicide, and more likely to face longer prison time for committing the same crimes, face stigma in careers like nursing and elementary education, and are liable to face stigma and even mockery for being raped, especially if they were raped in prison.
The problem with the "men's rights" movement is that it has chosen to blame all of these injustices on feminism, and spends far more time attacking feminist causes than actually helping men.
This. If the MRAs actually did stuff about male-centric problems in society it would be fine. Instead it's just a club of guys bashing women and blaming feminism for their inability to get laid.
