I can sympathize with why you would think this. I am also not saying you are wrong per se, but I want you to know that many leftists with seemingly strange opinions have spent much time analyzing and considering the stuff they are vocal about. That does not mean they are automatically right, but it could mean that to understand their positions fully, in order to do things like evaluate bad or good faith discussions, more effort is required than usual. Hence I think you might be in danger of mischaracterizing those you think you disagree with. Ultimately, that might contribute to you having stances that could disagree with your values.

As a personal example, one thing that I had to spend a lot of time thinking about was the concepts of violence and authoritarianism. I have deep aversion for both, but also a clearer idea of what they actually are than I had before, with the consequence of some different stances on a range of issues.
