I had, in fact, heard of the White Terror, and the suppression of the island's indiginous people. I had not heard of the Gwangju Massacre.
There are two reasons why they aren't mentioned as much as Mao's atrocities. One is that those countries are our allies, and as a result we are more willing to overlook their faults. And I don't think that's necessarily right, but it's part of human nature to overlook the faults and flaws of friends and allies. But the second reason is that, even ignoring those effects, Mao killed far more of his citizens (and far more per capita), making it a much more interesting and disturbing event in history. The atrocities of Taiwan and South Korea come across as "run of the mill authoritarian leaders violently cracking down on dissent" while the atrocities of Mao's China are on a whole different level.
FWIW, as far as dictators and genociders go I think Pol Pot gets the least attention relative to the scale of his atrocities since he wiped out 25% of the population, and in extremely brutal and arbitrary ways.
