The financial support point seems like it could have some legs. The other ones aren't terribly convincing. "They went on the bad guys show" or "they said the same things the bad guys say" isn't all that compelling to me.
I don't see how any of it rises up to "lol they've been completely debunked"
As someone who has no dog in the Russia/Ukraine fight (other than my tax dollars), I never liked how if one side said the sky was blue and you entertained the idea, suddenly you love the enemy, and you're parroting their talking points. Nevermind that neither of them are my friend.
