I think most of the taboo on swearing is absolute bullshit, the only time I agree with the taboo on words is in the case of slurs, unless someone is using in a reclaimed way, though that said I think some slurs are unclaimable as their particular composition implies something absolute disgusting, like some of the slurs for trans women quite a few are disgusting and implies things untrue therefore they are unreclaimable, and many of those need to just die out you can prolly guess which ones.
