That is the original meaning of the word, yes. Just as the word 'gay' can mean 'happy' its meaning has changed over time to represent homosexuals.
If it's the word itself you're getting your knickers in a twist about then fine, would you prefer it if the paragrapgh read 'However, refusing to marry a gay couple, while legally permissible, is still despicable and they should stop. Although, compared to the jihads, crusades and child-rapes I suppose a bit of bigotry's not that bad.'
I've never seen anyone so upset about a simple bit of etymology.
