Yeah, except it gets more complicated than that. Google wouldn't necessarily be promoting it either. As their algorithm looks for popular searches. Terrorism seems to be an overly used word for comparing protests to terrorism.
As an example, I live in a pretty red state. I would consider my self democrat/liberal in this state. When the George Floyd protests were happening a lot of people in my state were referring to the non-protest raids as terrorism. Despite the fact they will all defend the very clear terrorism on the capital as an attempt to save the U.S.
Point being you take the word protest and terrorism. You set it side by side as an exaggeration for literally anything half the the country disagrees with and boom you get popular terrorists searches.
I also don't think Google isn't at fault since their algorithm is designed to continue feeding that kind of content and the deeper you go the more ingrained into content you get and the more insane it gets.
