Socialism

What you’re calling “socialism” is not socialism You’re talking about capitalist reforms. Socialism is the end of private property and wage labor which can’t be established through parliamentary transition due to the class nature of capitalist society - ie. the dictatorship of the bourgeoisie.

I haven't described what my conception of socialism is, just described one mechanism socialists have used and are trying to use to enact the changes we want. So far we have not ever seen a developed capitalist society transition to socialism, so I don't think parliamentarism has been ruled out as a mechanism for that happening any more than anything else has been.

This is all very tangential to the actual issue. It doesn’t really matter from the point of view of the struggle whether they’re controlled directly or indirectly. You’ve been nitpicking very insignificant points the entire time without addressing the main points and it’s starting to look like trolling at this point.

I think this point just seems insignificant because you're not getting what it is. Unions are not controlled either directly or indirectly by the Democratic Party. Instead, unions are one of the social forces that control the Democratic Party, which is ultimately an incoherent mess of forces and agendas stuffed into a big tent by the oppressive American electoral system that only really allows for two parties.
