Even dishonest histories of the KMT are rarely so dishonest as to claim the ROC was democratically governed, however much they try to whitewash the mass killings. Disinformation has to be plausible to be effective.

All this arguing about what the KMT did and the relationship going back to the ROC doesn't matter. Today Taiwan is a democracy, is no threat to anyone, and deserves every right of self-determination. Democracies should work together to collectively protect each other from the authoritarian countries that want to take them over and destroy their democracies.

"going back to the ROC"? It sounds like you aren't aware that the ROC still exists; it governs Taiwan. Some of the things you say are true but it seems clear that this is purely by coincidence, not a result of any knowledge you might have of the topic.
