I don't consume this sort of content, but in general, I don't think "democracy" is the best way to judge niche fetishes. Decades ago, the majority would have voted to exclude gay porn. I personally enjoy hotwife and cuckold content. I've been pushed out of communities where the thought of ones partner sleeping with someone else makes a lot of people uncomfortable. When I see the community voting for or against fetishes it makes me uncomfortable, because I wonder when one of my kinks is next.
Voting on content inclusion or inclusion will lead to a tyranny of the majority. Kink acceptance should not be a popularity contest. Instead we should seek a principles based approach that embraces inclusion and tolerance while still staying within the bounds of the law. At the same time we should encourage the lemmy devs to build features that allow users to avoid content they don't want to see so that we don't need a heavy handed top level approach.
