Can’t have a show these days with a homo or a lesbian, preferably both, thanks to the LGBT radicals. Further, they must be portrayed in the positive light.
Of course, Julian Fellowes, the writer of that show, is a conservative I hear.
I don't mind the occasional gay character; I've known some very delightful gay people. It's not like they don't exist. I've also known some very disturbed ones. But for Every. Single. Show. to have this gay plot line... it's getting tiresome. They are a tiny fraction of the population, regardless of their infantile need to believe that absolutely everyone (particularly every handsome man) is GAY or a wanna-be GAY.
