I suspect linking is against site guidelines, but if you search for 'degenerate' you will find at least one example of a trans person being called such in an unflagged comment.
It is not against site guidelines, as far as I know or have seen
Searching for "degenerate" on the page leads to a single comment for me [0], and that comment uses it completely impersonally:
> When I was a baby queer in the mid 90s, it was functionally impossible to talk to gay adults in person at all because the AIDS epidemic had convinced society that all gay people were dangerous degenerates.
It's perhaps not against the guidelines per se, but linking to flamebait comments does tend to lead discussions in the wrong direction, and tends to be discouraged by mods AFAIK.
