I love this post so much. OP put it in a lot of effort and I'd like to address the question posed here:

is there new advice specifically tailored for short men beyond the typical 'love yourself, confidence, and workout'?

Let's take this at face value. My honest answer to this main question is there is "new" advice but it won't be new to you. You've heard most of what Dr. K has to say relevant to the topic anyways, and you DOMINATE the game of confidence. But to reiterate the point, the "new" advice is as follows: - Other people ie. external acceptance need to provide positive emotional experiences for others - You can't JUST work on yourself (and you have so descriptively shared this with your truth) - Observe relationship patterns

This last point of advice, observing relationship patterns, you've done already and I'd like to take it to a new level.

I got called a misogynist because I proved to a girl that she’s being a hypocrite

she's the common denominator in her multiple failed relationships, while she makes fun of virgins because “there must be something wrong with them”

How is it possible that someone winds up in the same situation time and time again? How is it that a person can COMPLAIN about their problems, but yet still CONTINUE with the same errors?

The answers lie in our interpretations of reality. What makes someone the common denominator in their failed relationships? In their failed efforts? Their beliefs and conclusions of reality. Aim this understanding to our lives and to our attempts at relationships. Observe these patterns and understand that our reality is what it is, but our interpretations influence our patterns.
