The only point being demonstrated here is that you fail to see the explicitly authoritarian actions of the parties Musk supports in the US (Republicans), Germany (AfD), Hungary (Fidesz), etc., and do not understand that in democracies the branches of government (legislative, judicial, executive), and the institutions of society (press, academy, finance, industry, sport, religion, social) are all independent. In contrast authoritarians coerce or corrupt these institutions to serve the executive.

If you can't see those authoritarian actions by the parties Musk supports, you are either willfully ignorant or just plain obtuse, or a willing authoritarian proto-fascist.

And no, your point is still wrong; there is nothing wrong with changing ones opinion of a public figure when he comes out supporting authoritarianism
