"I drift any farther left, I’m going to fall off the side of the earth near the international date line."
No, you won't. There is no edge. The political compass is a sphere (as you hint at using the globe). You will end up supporting the same policy of those "dangerous fascists" and just call it something else.
Your misery is rooted in your false expectations that the world is just and for some reason you've never grown up out of it, hence the communist sympathy and blaming of “the system” for your unhappiness.
Your post-modern perspective that suggest culture and borders don't matter isn't rooted in the reality of human nature.
You have no purpose because you have no ideology, no belief system. Your so called leftism is a guise masking your nihilism and your nihilism is the root of your misery.
