Like if a person said 'Every Disney movie has only green cars in it. There are MAD other color cars on the road. I'ma slide some red cars in here.', I'd have no issues with that.
If a person said 'Every Disney movie only has white people in it. There are MAD other races of people on Earth. I'ma slide some black people in here.', I'd have no problem with that.
If a person said, 'Every Disney movie only has abled people in it. There are MAD other people who are not abled. I'ma slide some disabled people in here.', I'd have no problem with that.
So when a person says, 'Every Disney movie only has same-sex couples and heterosexual people in it. There are MAD other types of couples and people. I'ma slide some gay people in here.'...I have no problem with that.
