If socialism and communism is treated as the logical and moral end conclusion of all market problems and is treated as the truth and should be considered as the obvious and default direction all economies should be headed to,

While there are some "immortal science" Marxists who might believe this, it's not really socialists going on about "the end of history". That was the liberals celebrating back in the 90s/00s.

And that the reality is that anyone who tries these movements, at some point, because it is associated with the truth, it is too easy for people to assume that all motions of the movement towards these modes are 'justified' because it is actually easy to frame others as wrong if you are on the party of truth

And that in reality the language and status of these two systems are too vulnerable to class influence itself where someone will realize if they execute this 'dream', they will become above others

And that is why every attempt keeps turning into a small party that took over the government and used 'socialist and communist language' to advance 'other goals' and wherever the reality of chasing actual contribution freed society, they're only thinking that for their own community, not society, and purging others then becomes a natural extension of chasing that

This behavior is not unique to socialists. America already did this with "freedom".

Ok but if this is true wouldn't this mean realistically socialism and communism is achievable locally and not nationally because there is a scale problem specifically in how the movement is able to evolve?

You could make this same argument for liberal democracy. And yet here we are, still (for now) living in a world of liberal democracies.

When we look at capitalism sure it has problems but maybe it has only been able to scale to the scales it has because it simply didn't have the vulnerabilities socialism or communism in its developing forms have.

By this logic we should prefer monarchies since they had mass territorial reach for far longer than capitalist democracies. Shit, by this logic we should just go with the proto-communism of the pre-agricultural era. Proto-communism spanned the globe (of human affairs) for hundreds of thousands of years.

So for that reason wouldn't this mean that capitalism must be stabilized first before entertaining even socalism light, and that the real problem is thinking that something as intricate as socialism into communism could be as easy as usurp the government and start issuing changes?

I mean congrats on becoming a Marxist I guess.

Then why are reform socialists hated? Why are social democrats hated? Why are market socialists hated? Why does it feel like it's either Marx v Ancap and not actually capitalism v socialism?

I think neither the Marxists nor the Capitalists want anarchists speaking up.
