An expression of sorrow is not in fact an apology. It's just an expression of sorrow. What it certainly isn't is an explanation of his helping to strip gay people of a civil right. It isn't a claim that he has changed his apparent view that gay people are second-class citizens. And isn't a promise that he will no longer work against the civil rights of his employees.

I also have never stated that all we need to know is one action of six years ago, and have several times stated the opposite.
