I think there was a culture shock when federation first hit. We had a ton of 'engagement' from people who were using ableist, racist, and transphobic slurs, which brought out strong reactions from our community because we believe its important to shut that stuff down on solidarity with our comrades. And as things got heated I think our willingness to believe people wanted good faith debate eroded.
We do love a good dunking though, and I think overall the community has a lower threshold for going full pig poop balls on people than I would prefer.
I think people who are motivated by Ukraine are often doing so as an expression of their partisan identity (evil ruzzians colluding in our elections/sleepy joe turning us communist), not as a consistent position you could leverage into a long running project. I might be wrong about that but no conservative I've heard on this topic has a position that makes sense outside of partisan teamsmanship. Except maybe like Mearshimer, but he's not representative of the base or a popular upswell in sensible realpolitik calculation among suburban white people.
If the issue is popular among right wingers because they want to lurch further right I'm not sure how you coopt that. You could coopt genuine antiwar sentiment. Can you do the same for "NATO is (((the globalists))) trying to weaken us so the Chinese can take over"?
