I legitimately respect your point of view.

But effectively if implemented as you suggest we're at a conclusion then that small dick jokes, even as a passing reference to the overwhelming societal norms of the past few decades, are a protected class?

In the 90s, many folks called stuff they didn't like or thought was lame "gay" pejorativly. I understand the perspective you are trying to hold here in not perpetuating a similar bias towards the less-well-endowed (LWE). But this is a group that ostensibly includes half the global population as possible members, and the colloquial usage of "big dick energy" has nothing to do with actual dicks. A man with a 2" Johnson can have incredible big dick energy. A lesbian who just laid down the law and owned a task can have big dick energy. Conversely someone always scared of others, or hateful just because things are different is not acting with confidence. They're giving off the opposite, small dick energy.

There's no hate here towards a protected class, or even toward LWE folks. It's about a concept rather divorced from the actual physical circumstances.
