I think the idea that what our revolution needs is for people to be more disillusioned with the system is a bit off. Do the research, this is already happening (here is the first result if you search "faith in democracy" just as an example).
I accept psl's tactics in a live and let live sort of way, but that doesn't change the fact that dsa has done more for general awareness of socialism than any other socialist group.
Your experience with your specific dsa is sad (though i doubt these organizers are working directly for the dnc) where i live it has been the complete opposite where the dsa is becoming a predominant force in local politics.
Just sent this to my partner, gonna see how long it takes for them to dump me
