Sorry, no, stalking people online is downright off-putting to anyone from the real world. Having non-political endorsements from people you (and, if you believe it, I) deeply dislike doesn't warrant this kind of treatment. You've simply worked yourself into a froth to justify doing it to someone you really don't know. What right have you to be 'concerned' about the Youtube videos someone watches in their private life? This is normal only to the social-media-mob-socialized.
This sort of runaway justification is a very common pattern from the self-righteous, across the political spectrum. It's why I need to use a throwaway to talk about these issues, even with people I ultimately agree with. Consider carefully how few hearts you've changed with this strategy.
So, yeah, I reiterate: go outside! Smell the roses! I'll follow my own advice, at this point.
