Agreed. However, at the same time, this happens with almost _everything_ on YouTube. I bet you 5 Fake Bitcoins that if you watch a lot of Left-leaning videos from NYT, Vox, and others, that you will be in your own rabbit hole.
As a left leaning person, absolutely! I viewed a few of hbomberguy's tamer videos, next thing you know I've got videos with commenters suggesting we bust out the guillotines. But hey, thats what gets the eyeballs and the ad revenue flowing!
