Sure it shows disrespect; but, he was returning disrespect for disrespect, so I'm not sure you have a leg to stand on.
Moreover, seems you graduated from UT in 1972, right? Now, maybe I am wrong and overgeneralizing, but unlike college admissions over the past fifteen to twenty years, attending university in the 60s and 70s was largely reserved for the well-to-do and privileged.
So, maybe you, too, were also a "spoiled rich kid"? Or, maybe you were an exception? And, sure, there were exceptions just as many Catholic School students have their tuition waved if their parents cannot afford the tuition, so long as their parents tithe regularly to the church.
But, you've discounted that option, with your assertion that we must all just be spoiled brats who are ultra-liberal because we grew up privileged. So, as long as you are discounting such possibilities, I will merely assert that you, too, were a spoiled rich kid who grew up privileged; yet, one of your privileges, growing up in the 50s and 60s, was that you were very obviously treated as more of a citizen and more worthy of respect due to your whiteness and maleness. So, you've probably carried that with you, which probably colors your ******* stance on immigration.
This is a fun game, yes?
