Doesn't a lot of it come down to having to choose between only two parties?

It's unlikely that most people will agree with all the positions of a party, so they choose the one who most closely aligns with their highest priority issues.

Perhaps trans policy is just a lower priority issue for your dad. His voting may be illogical based on your priorities, but may be the rational choice based on his ranking of issues.
