You can look anywhere and come up with a range of definitions.
Having or showing a dislike of or prejudice against homosexual people.
Where is his prejudice or dislike.
His view is not expressing a dislike or hate.
Like I said, I want my DDs to get married before having children. That's something I have expressed my view of to them.
That doesn't mean I hate anyone or show a prejudice towards anyone who has kids and isn't married. It's just not my choice and not a choice I'd want them to make.
Far more important is the way someone behaves in their daily life, than their feelings about sexual orientation.
I have a diverse range of friends and they make a range of personal life choices. I would not make some of those choices myself... but I accept individuals for who they are and their right to individual choice, whatever that may be.
I'm black. I have white friends...I know some of them would never have a relationship with a black person, but that doesn't make them racist to me. It's their individual choice. They don't have a negative view towards me and they would never treat a black person less favourably.
