For those uninitiated, menkampf was a parody subreddit where they took any anti-male statements and replaced the word "Jews" with it. For example:

"Kill All Men"

"All Men are Trash"

Replaced with:

"Kill All Jews"

"All Jews are Trash"

Basically, it was to show how hating on people for based on their characteristics was bigoted, no matter who it was against. It was a great subreddit in showing the hypocrisy. But unfortunately, it has been banned and there hasn't been any attention.
