We have no idea what the prevailing norms and taboos will be 20 years from now. Something you write today that is benign and uncontroversial, might be utterly offensive in 20 years, and all someone has to do is dig back in the internet archives and find it. I think back to 20 years ago, and I know I've told some (at the time) harmless, slightly off-color jokes, which today would get me fired instantly. You don't know which way the sensitivity wind will blow in the future, so your only safe play is to limit yourself to Rated-G "genuine, kind, and with empathy" speech, as you put it.
