The assertion being made in the OP screenshot though isn’t that land reforms should not take place, but that they cannot take place now under capitalist rule. The examples you are giving were done only after socialists took power right?
“We do not live under communism and neither do indigenous people. this is simply creating a new place for the fundamental contradiction to occur”
and then there’s also the rest of the twitter thread where I think the point gets made pretty clearly.
ok Bolivians and Nicaraguans do not live under communism either, yet land back policies very clearly took place giving indigenous people this autonomy. land back is not privatization of public land, its just one very reasonable policy for socialists to support, this isnt complicated stuff!
