Tom Scott's dicusses in this article
https://www.tomscott.com/gender-neutral-pronouns how negative comments and dislikes on his gender-neutral pronouns video started getting worse around mid 2017 (while the video was published on 2013).
It would be interesting to see whether that trend repeats on similar videos and if it can be explained by some 4ch*n campaign/The_D0nald's campaign.
