Can't really talk to the disrespect but an ex was about 6 inches shorter than me, and she commented how she loved how much taller I was and having me around made her feel safe and protected, and while I hadn't thought about it at first it was nice to be appreciated for our differences.

Didn't really have many fights and when we did argue it was usually sitting down on the couch so the height difference was moot (though in hindsight she would often hop up to her knees when trying to make a point so maybe subconsciously going for the height advantage?)

I don't actively seek out shorter girls but most women interested in me certainly seem to be shorter than myself by a few inches, only girl my height I dated was very short lived since we quickly found out we didn't have compatible interests or personalities.
