What are your reasons for thinking he was on the Right?
My understanding is that everyone who has publicly spoken about him has indicated that while he was raised in a Republican family, he himself held strong Left views. His friends/classmates have indicated he had become very vocal about this and regularly got into arguments over it. He was in a relationship with a trans individual which is a decidedly Left behavior. More than that he murdered a Republican poster boy because of his ideology (as indicated by Tyler himself).

Likely based on his texts with his transwoman roommate.
