I'm thinking about doing this and I'd like to know the legalities of it. I'm not trying to get brought to the Supreme Court over discrimination, like Masterpiece Cakeshop did, for refusing to do business with a certain group of people, on the basis of the owner's beliefs. I'd be refusing to do business with a large group of people, on the basis of my beliefs. MGTOW is a belief system, wouldn't you say? Its a set of principles or tenets which together form the basis of a religion, philosophy, or moral code.
