Its not that people in DSA arent committed, all the chapter are run entirely by volunteers, and there is an enormous amount of work and organizing that goes on. Its just that people can easily join en masse and start getting engaged and educated and trained, which is what you need to build a mass socialist movement. Theres certainly difference between dsa and psl, tho ive been happy to meet and organize with comrades in the local marxist caucus in dsa. For me the interest is with DSA's influence though, as it can make a large impact nationwide, but we gotta also make sure the org is orienting itself the right way too.
