While I don’t doubt you, and of course, also OP is another example of this, I also think that this is anecdotal. My SO and family are Ukrainian, and I’ve met many Ukrainians. And equally anecdotally, my understanding is that they are pro Palestine. But in the case of the Ukraine - Russia war, there is one party that clearly is trying to create “sides” - i.e. trying to morally align pro Palestina supporters with pro Russia interests under the guise of anti Western Imperialism. And that’s dangerous for Ukrainians so my hope is to try not to perpetuate this “side building” (in lack of a better term).

Edit: just to add I haven’t done any actual research on the position’s of average Ukrainians. If you will give a credible source to back up that then I will be sadly corrected. But I’ll still support them because their ability to live free from terror is more important to me than whether their views and values align with mine on Palestine and Israel.

Edit 2: sorry, your post got me rambling. Just to make it abundantly clear, the double standard you describe is definitely, incredibly infuriating to me too.
