I don't understand what your point is. The people of Taiwan (or the Free Area of the Republic of China, or whatever you want to call it) today, in 2019, don't use a Civil war from 70 years ago as their main reason for not wanting to be administered by a communist dictatorship.
Because that's simply not the lens in which it's viewed in Taiwan in 2019. Mainland soldiers and refugees were well under half of the population of the whole island- and that was 70 years ago.
