Has he hurt anyone? killed? imprisoned? injured? threatened? Stalked? preyed upon? or been in general mean to someone?
If being of a different opinion and expressing it is enough to be labeled despicable human being, I don't know if I would call that fair.
For me, that's like calling Linus an despicable human being for criticizing Gnome 3. It's a really strange use of the word despicable.
