All of these streamers suck anyway. I don't care about their personal life but I care about the views they are peddling and the impact their word has on their communities.
The Right streaming sphere also has a few despicable characters, but I don't see the same witch hunt for them as for Hasan. iirc some also have abused animals if that's your specific trigger.
This is simply identity politics and why political discourse is untenable nowadays.
For the dog part, I think it's horrible to use a shock collar, and on the same level, police dogs and horses are also abused in the same way. Western culture sees eating dog meat as immoral, but some see eating any animal as immoral. Everybody has their own moral compass for this and I don't go policing others for their views.
