There are so many levels to this. First, not everyone in NYCDSA is an opportunist, but they are a minority. Second, education is piss poor in the US, critical thinking skills are abysmal, and red-scare tactics are very much so alive here. Many who engage in opportunism do not realize what they are doing so as they are simply uneducated and tailing “what works,” which hasn’t been explained outside of truisms. They fall for ideas of dual-power, reformism and revisionism because of this lack of education and a lack of framing Marxism as a science. However, if they were educated, many would be actual Marxists. DSA does have a framework for enforcing education and other leftist thought, and there have been successful changes to National DSA bylaws (like ones that remove barriers to Democratic Centralism). As with all dialectical processes, it takes time to build, but there will be a quantitative change.
