allergic to the idea of existing with other human beings and have zero concept of shared space. Frankly, I find this opposition to people reclining in a reclining chair to be comically ridiculous.

Well as someone who will have their knees crushed when you want to take more of the shared space for yourself, this is exactly how I view your argument. If I were short then I probably wouldn’t care. I dont lean my seat back because I know exactly how it is which seems like a much better way to be a steward of shared space.
