If people who didn't golf were considered subhuman and needing of "saving" then non golfers would develop a supportive community too.

Please don't confuse "community" with "religion." Bronies also have those things you mentioned but not a single person would classify being a Brony as a religion.

(If you aren't familiar with the term, a Brony is an adult or teenaged male fan of the children's show My Little Pony: Friendship Is Magic: https://en.wikipedia.org/wiki/My_Little_Pony:_Friendship_Is_... )

Same with ideology, not all ideologies are religions. Believe that the Earth is flat is an ideology but not a religion even though personally having that ideology may be based on religious beliefs. Same with veganism.
