I think it depends on the things you watch. For example, if you watch a lot of counter-apologetics targeted towards Christianity, YouTube will eventually try out sending you pro-Christian apologetics videos. Similarly, if you watch a lot of anti-Conservative commentary, YouTube will try sending you Conservative crap, because they’re adjacent and share that “Conservative” thread.

Additionally, if you click on those videos and add a negative comment, the algorithm just knows you engaged with it, and it will then flood your feed with more.

It doesn’t care what your core interests are, it just aims for increasing your engagement by any means necessary.
