i have never understood this phenomenon of people who have graduated from atm-commerce, kingsville, or corpus that claim to be part of the main branch of atm so to be.
Texas A&M actually encourages that. My son is a TCU alum, class of 2010, but got his JD from A&M Law. I remember going to some kind of function for parents and family where they did whole the "Aggie tradition" spiel, from the opening "Howdy" to the class ring. It was half disgusting in its arrogance and half just plain damn hilarious. The arrogance was in the presumption that all these law students were going to forsake their own alma maters for the "privilege" of taking on the Aggie mantle. The hilarity was in how seriously these Agheads actually took themselves. I had to stifle the urge to snicker many times.
When my son graduated law school, his Aggie aunt and uncle made him a gift of an Aggie class ring. It was a generous gift and he was appropriately gracious for it, but he's only worn it when job interviewing (in case there's an Aggie in the hiring hierarchy) or at law school alumni events. He has five or six articles of clothing connected with A&M Law in his closet, but he has an entire row of TCU purple. And he unapologeticly says, "I'm not an Aggie, I'm a Horned Frog and I'll always be a Horned Frog."
