I've seen is people ranting about hygiene as if men don't know how to wash their dicks with soap

Same reason female feminists call men predators. Because the only ones who will associate them with feminists are.

As far as I'm concerned pro-circumcision people are crazy and have a lot of issues, end of, leave my dick alone.

They want to persuade themselves that their body is fine. I actually got a very long rant in a PM which was quite amusing a while back, with all sorts of crazy.
