Bro, you're using way too many words to say that you benefit from the status quo and don't want to change things too much because you're afraid that it might impact your personal comfort. You want to move incrementally into a planned economy just in case, and I get that. I understand where that fear comes from. But the time for incremental change was 50 years ago, the current climate crisis demands we change now or face extinction.
I understand that socialism and planned economies don't fix issues of racial and ethnic hate. It's the responsibility of socialists and other leftists to have a healthy dose of intersectionality when talking about creating political systems, because discussing how to make sure minorities aren't negatively impacted is essential to the system succeeding.
I'm actually kinda offended by your suggestion that "we should try something else when creating a socialist society to ensure minorities are heard" is equivalent to an ethnostate. Actually what the fuck. That's a disgusting comparison and I don't understand at all how you decided they were equivalent.
There is stopping something from creating socialism in the status quo, and it's called capitalism. Capitalism has, does, and will continue to fight anything that challenges the status quo. The ideal for capitalists is to recreate a feudal society, child labor and all. You talk about instability within former socialist nations, but never draw the line towards the endless attacks placed on those countries by the imperial core. Most recent example? Zunzuneo, an astroturf social media site created by USAID as a CIA front to destablize Cuba. There's also the 1990 US Appropriations Act, which caused Yugoslavia to collapse into reactionary ethnic hate that resulted in the Bosnian genocide. You point to failures of socialism as if it's a fundamental flaw, but never examine the reasons for why those nations failed. If you did, you'd see attacks from the imperial core as well as mistakes from the local government being the point of failure, not socialism.
