You’ll never agree on every issue, but you can always agree on at least one issue

Which is why he shouldn't do whataboutism purity testing in a thread about Zionist censorship?

You're missing their point. Two things we know about Hasan:

1. He's an influential and outspoken critic of human rights abuses, which has made him a target of the people/institutions responsible
2. He might have used a shock collar to train his dog which he might have used on stream

Even if the latter is true, giving more weight to it than the former seems pretty disproportionate (imo).

As a vegan I abhor violence toward animals (and humans) and was dismayed when I saw the original clip. But after being absolutely pummelled with bs outrage "analysis" videos, to me it became clear that there was a coordinated campaign being waged to smear him, very likely from those whose abuses he criticizes.

If he uses a shock collar to train his dog, I do not like that. Ultimately, my conclusion though is that I do know that he has consistenty taken a stand against fascism, and to me it is clear which of those has more substance.
