I read an interview with Del Arco in a 1990s Trek magazine, and the backstory of the origins of High in what he witnessed in the AIDS-related dementia of his partner never came up. His orientation, for that matter, never came up.
I really do appreciate that this can surface now.
Del Arco seems to be a genuinely nice and interesting man. He has been an activist for gay rights , and has also been involved in environmental issue and for the rights of immigrants. Hhas worked for three presidential campaigns and he served as an Obama Celebrity Surrogate for the 2012 Presidential Campaign. He was born in Uruguay and his family moved to the US when he was ten.
His most notable role is in acting career besides playing Hugh has been as Dr Fernando Morales in The Closer, and in Major Crimes. In those shows Dr Morales was definitely a gay man.
