The Thai election results is very disappointing. The youths have overwhelmingly voting the anti-China party. They are making the same mistakes as the youths in all other democracies. The US is the master at fooling the naive youths in any nation. It worked in Europe, HK, Taiwan, SK, Malaysia, and Myanmar. American control of media and pop culture is just too powerful. China just doesn't do psyops, and that leaves the US to dominate the hearts and minds of any youths. Very frustrating, but this is the hard truth.
But let's look closer at Thailand. While there are no doubts that there are fervent anti-China idiots in Thailand, this election is actually a vote against Prayut Chan-o-cha and his cronies. Not a true vote against China. Like it or not, Prayut is not innocent at all in this affair. He is among the list of China-friendly, but also corrupt leaders. People like Najib Razak, Nawaz Sharif, Myanmar junta, etc. These leaders are easy to topple because their people generally hate them. Thailand's economy is not the worse in ASEAN, but it operates like a typical SEA economy. Corrupted, elite-favoured, and a large wealth gap. There is a general lack of upward mobility for the youths and the low income groups. Not the worse in ASEAN, but it's serious enough to piss off the youth.
Nevertheless, Thailand is not a true democracy. I suspect that the new Thai government will be coalition of the pro-US and the Shinawatra party. They are likely to talk to the military and royal faction and reach some sort of compromise. No extreme change in policies. Otherwise the military and the monarchy will loom over them in the background.
