This might be true for me, but I don't want to put that on all Democrats. Yes, there are things I don't want my mama knowing about, but everyone has those things. Take Trump for example. He said to grab women by the pussy on live TV. Do you think that's something his mom would be proud of? How about Republicans who oppose abortion yet force their mistresses to get one? We all do things our mama wouldn't like. What this stereotype is referring to though is marijuana and being gay. I'm sure of it, but that's because I'm very well versed in coded language.
"Your mom would be so ashamed that you vote for basic human rights and allowing others to live the life they want to without the judgement of Christianity, which should be left out of politics." That' what I really hear when I hear that criticism.
