What about anti-Taiwan imperialism in China? Because Taiwan claims all of China and the 7 dotted line.
Taiwan has to maintain these heritage claims because repudiating them would effectively be de facto repudiating the 'one-china' agreement and equivalent to declaring independence, which China would take as a casus belli. It's a farce. No-one, Taiwan included, genuinely believes that they can get any of that land, nor that it would be desirable to pursue it.
You cannot be against Zionism and support Ukraine at the same time.
This is silly. So you assume every single person who supports Ukraine defending themselves against Russia is automatically pro-Israel?
