If you use one of those words in the title, and someone gets offended by it, can they report your comments for "using slurs"/ "hate speech"?
I know most of the users and probably most of the staff who read this will say "obviously not", but if it was significant enough for the site to change the tags, the next logical step would be to ban it's use in comments. Even if it's not ban-able yet, It almost certainly will be in maybe 5 years if the current political climate keeps going the way it is and if enough artists/ users threaten the site.
