here is a taiwan china history:
after the last dynasty of china, china was basically GTA. groups kill groups that kill groups. but then second world war happend and japan was like lets massacre massive amount of people. so then there were 2 groups who were dominating china and were also fighting each other and japan. one was KMT and the other CCP. so after a while of fighting each otehr the KMT and CCP controlled most of china except the japan part and then said hey lets to peace and shit. KMT and CCP controlled about equal amounts. then USA nuked japan and japan was like "oh no we lost" and then KMT and CCP was like "fuck this shit lets all invade the japan part of china and battle each other over it" and so they did. CCP was communist so it had massive support by russia. CCP pressed KMT on the taiwan island because of russias intervention. non of the 2 were clear rulers of china. so taiwans official name was republic of china and china was the peoples republic of china. UN be like nonono only 1 representative per country is allowed and so taiwan was the representative of china in the UN. so far both are dictatorships so far. then KMT was like lets not do dictatorship and then now we have this 2 major party system in Taiwan as we know it. then UN was like "china has big economic interest to us" and threw taiwan under the bus and said "ok lets try out CCP as representative of china"..... CCP never set foot on taiwan and hence has no arguement to say this is china. not even during dynasty this was very inhabbitet. there were indiginous taiwanese people living rural lifes until KMT showed up. since neither CCP or KMT were removed, there is also no clear winner of the conflict between the 2 nor is there a clear ruler of china. one china 2 system basically means we agree there is 1 china and 2 leaderships but we agree to disagree on who the true leader is.

what is now changing though is before tsai the stance of taiwan was like "we are the true leader of china" but tsai now more is like "let taiwan be taiwan and let us be independent nation".

ur comparison would be more like as if russia supported bayern to invade all of germany and let germany only live on its small island helgoland. in that case CCP in bayern. and i would not want to live on helgoland.

about human rights:
for 20 years tens of thousands of people were organ harvested for organ transplants and more for medical research used and killed. tortured and used in concentration camps as slave labor ensuring businesses to always produce cheaper than the rest of asia (you didnt think businesses stay there for their anti foreign policies and justice system?). also saying "they are right to cause suffering because we suffered more" is a weak argument. why need to suffer? why not stay true to one self without being swayed towards china or USA when they are both bastards.

germanys actions made trump move much of their soldiers to poland because we dont buy enough USA weapons. also what shocked me was we paid for housing for US soldiers while other countries USA pays for its bases. so i think we stopped that. we also own half of the 2 keys needed to activate about 10 nuclear weapons incase russia tries somethin funny with their nukes. neither USA or Germany can decide to shoot them but only them both, which would need agreement from both sides which would not happen unless russia is trying somethin funny with nukes.

biden would probably be worse than trump because he would find agreement with congress without them blocking it, while trump would get blocked in congress. they are the same. plus trump is rediculous enough that europe is finaly moving its ass to make a european army to become more independent from NATO.
