A dominance hierarchy will exist.
It’s what makes relationships and business function.
It also makes BDSM thrilling for participants. But that’s consensual.
Mutual effort, mutual benefit. A voluntary exchange.
When dominance is forced, it’s abuse.
Some people want to govern.
Some prefer to be governed, others need to be governed.
These people should not suffer prejudice.
Assuming their master/slave routine does not interfere with the lives of free people, they should be afforded the time and place to indulge their fetish.
