I just realized that I definitely started hearing the first 3 words/phrases you included right around the start of 2016. Though, it wasn't through political debating or any content like that. Those phrases started popping up in the commentary and skeptic channels on Youtube right around the time. Usually when dealing with subject matter retaining to Youtube drama between channels. I dunno how I didn't notice the lack of hearing those terms up until then. Probably because I'm a lobotomite who only thinks about handing out fat ass smacks on vidja games.
