I think maybe we have different approaches. I think maybe you are looking for a type of ideological purity in what ideas you consume. A type of pursuit of perfection.
For me, I know who I am and I know what my values are. Given that, I don't care whole lot about source purity. I'm not afraid that reading something is going to make me wake up one day with a desire to make life a hell on earth for outgroups, or to cancel democracy.
I pick up ideas where i find them as they explain things better than my old ideas., I cast them off when new ones better explain the world around me. I'm not afraid of "not being right", nor am i afraid of becoming contaminated with mean-spiritedness. I'm only afraid of not growing and learning.
