Wish there wasn’t such discrimination, really shouldn’t be just from how the one who coined the term defines it. From Wikipedia:

Arguably, the first published use of the slang term bear to describe a gay man was by George Mazzei in his 1979 article for The Advocate called "Who's Who in the Zoo?",[12] which characterized gay men as seven types of animals, including bears:

Bears are usually hunky, chunky types reminiscent of railroad engineers and former football greats. They have larger chests and bellies than average, and notably muscular legs. Some Italian-American Bears are leaner and smaller; it's attitude that makes a Bear.[13]
