I'm 50/50 on it. If it doesn't go away by the time Trump leaves office in 2024 then it's here to stay until it inevitably implodes along with the rest of society on its own inconsistencies and stupidies like communism did. It probably will never go away anyway but be shoved to the background like it was back in 2013/early 2014.
Or hell, maybe it's lifecycle is like the Religious Right, just instead of us being in the mid-00s "fundies trying and failing to put creationism in the classroom" stage we're at the "fundies about to get Ronald Reagan elected" stage and we have another 30 years of this shit before it finally dies and it's FAR more powerful than the Religious Right ever was.
Too late for that, the ideology of globalism at the heart of Current Year makes sure Current Year must be spread globally, local culture be damned. And it already has, just go to Twitter and look up terms related to troons in any non-English language. Tons of Americanized Europeans and Asians out there whining about how hard being a troon is, complaining about sexy women, promoting BLM, and posting about how awful Donald Trump is.
