In any case, the same contempt for PUA, for the wrong reasons, did resurface in this discussion, such as here, and here.
Um, neither of those comments shows contempt for PUA, in my estimation. SarahC expressed confusion, and Alicorn made an observation about a group that merely overlaps the bottom-feeding layer of PUA.
So, yes, I still think you're worrying too much. What's more, I don't think that your protests have ever actually helped the situation - if anything, they create more polarization, and further the impression that you're a low-status male protesting the status quo is unfair to you.
Meanwhile, to the extent that your remarks are successful in scaring off people who'd otherwise participate and maybe get one of their biases overcome or a misconception sorted out, you're doing a disservice to everyone. How do you think people get any greater empathy, except by engaging with their wrong ideas, so they can learn that they're wrong?
So all the ominous saber-rattling isn't helping anyone -- not even you.
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
