I mentioned this just yesterday ... that this is a potential development out of "hate speech" legislation.
Cucks not only tolerate, but like to watch, another man make love to their wife. With all due respect ... the word "perversion" has definite meaning. Just as gay people here will say that while respectful gay relationship is an acceptable form of love, but pedophilia is beyond the pale, even for them. Per Freud, consider how sexuality drives not only individual behavior, but society and culture. "Passion" applies to many things.
So do Europeans have a "passion" for sado-masochism. SJW guilt, feminist guilt, if strongly held, has to have a sexual component. Bluntly ... I am X, so someone please $&%&^$ me. I don't deserve better? So again in a manner of speaking, your over-class is not only sado-masochistic, but they want to remove your "safe" word.
A danger of course is this "European" illness, crossing to N America, first to Canada and then to the US.
This is taking German dominatrices a bridge too far.
