This is the smart thing to do if your goal is to build a broad movement that achieves effective change in the real world. When serving emotions and looking edgy to your viewers online is more important than stopping the genozide then you should go the vindictive route and purity-test each person joining your side. Pragmatism is not selling well online, the crowd wants to see blood.
That means usually ot serves well to take such unappologetic stances with a grain of salt, while they sound strong, they are not usually effective positions for a broad societal movement. That btw. doesn't mean you have to forget any politicians positions earlier in this conflict. That's what I meant with "We can walk and chew gum at the same time". Makw the movement broad and keep track who was on your side early on.
