20. The DeVos Family – Orlando Magic
Let’s start off with Richard DeVos. The patriarch of a clan of homophobes, he was one of the most explicitly discriminative owners in US sports history. While the owner of the Magic, he flung millions into groups that want to remove existing rights for gay people. Talk about a way to alienate your fans.

Naturally, the rest of his family have similar views. The DeVos family probably wish that more fans hated them because they just don’t get enough in their stadium. People in Florida are more interested in the Miami Heat and don’t take much interest in the Magic at all. A few advertisements would be nice.
