All I can say is what I said in the post: I’ve heard that Rodger was a men’s rights activist. It’s possible that the people I heard it from were wrong. As for what his beliefs have to do with men’s rights, I don’t know enough about his beliefs or the body of beliefs typical of the contemporary men’s rights movement to make a judgement.

In any case, my general point was that spree shooters like him are so rare that they don’t tell us anything meaningful about the groups they belong to. Even if his beliefs were in complete lockstep with the men’s rights movement, then the men’s rights movement might help explain his actions, but his actions wouldn’t tell us anything meaningful about the men’s rights movement, any more than it would tell us anything meaningful about gun owners, the mentally ill, mixed race asian/white people, BMW owners, UC Santa Barbara students, or Game of Thrones fans.

The forums he’s been found to have posted to, a bodybuilder forum and “PUAhate”, are not connected to the MRM.

His youtube subscriptions, cited as proof of a connection, do not include a single men’s rights channel.

Furthermore, none of his beliefs have anything to do with men’s rights views.

There’s a reason why no source has been able to point to even one specific example of a connection to the men’s rights movement. There is no such connection.
