A powerful way to get people to be receptive is to get them to like you and consider you a font of wisdom. This does not require pushing them, just being available and usually correct and a person they enjoy spending time with. I would recommend honoring their wishes and reading more so that you're ready when questions do come down the pipeline.
Also you don't need to convince them all by yourself as a first step. You could try to get them involved in events they would find worthwhile instead and let the radicalization happen socially. If they are borderline anarcho-syndicalist then maybe they'd want to support a picket line, for example. Maybe there are people looking for help on projects your friend would find interesting.
I set my conditions for engaging and you seem uninterested in honoring them. Namely, that you reply to what I actually say and not go off in straw men instead, which is clearly just a pattern of dishonest guessed-at sectarian insults.
Please do your best to engage in good faith and in a comradely way.
