I can't help you - I've never felt I was discriminated against for being female, or even for being a bad golfer. I get a bit of condescension from older golfers, but so does my husband, so it can't be a gender or race thing.
However, my MIL, who was an excellent golfer, was denied admission to a golf club when she was younger, because they only let women join if their husbands were golfers, and her husband didn't golf. She ended up having her son, who doesn't really golf, join, so that she could use the clubhouse at least.
