Because even though it's nobody's business what people do in their own bedroom, it seems though it's everybody's business tio know how proud they're about it and have to advertise it in the loudest way! (Double standards)
Not just that. By giving such undue importance to the 1% of the population who happens to be sodomites, they are effectively discriminating against the remaining 99% of the population which is heterosexual. Protecting the rights of minorities is OK, as long as the rights of others are not infringed upon. But that doesn't seems to be the case here.
