Yes, I admit that sometimes people misuse statistical data, or the results of scientific studies, when making various arguments. Given that I'm conceding that point, what would I be arguing with you about on that topic?
If I see someone doing the above, I try to correct them. One of my motivations for writing longer posts on controversial topics in this forum, and trying to be rigorous in my use of research, is to provide information that might be helpful to people who want to understand these issues better in order to avoid those problems. Of course, my other motivation is to try to persuade yet other people that these issues are real and that they should care about them, but I expect I'm more likely to succeed on the first point.
I disagree with your analogy and rejection of "many leftist arguments" as a general statement, but I think it's far more productive to focus on specific arguments than some general assessment of the quality of "leftist" political discourse. Although, on the general topic, I'll point out that you keep making statements like this (cf. this post
). I'm happy to concede that liberals, leftists, Democrats, etc. don't always get everything right. But I roll my eyes at these posts because you seem oblivious to the fact that, by any objective standard, the state of the modern conservative movement is far, far, worse.
