Because unlike how many conservatives think, its not just a game of my side beat yours haha we win!
Public policy actually affects peoples lives. A friend of mines father had a degenerative condition that basically made him slowly lose control of his body over the course of a couple decades. First not being able to move around as well but eventually to the point where he couldnt even swallow. He died crawling across the floor toward the backyard where my friends mother was, trying to call to her for help. Stem cell research can help people with this horrifying condition. Trump and Pence are against stem cell research. They are objectively pieces of shit for that. They are objectively pieces of shit for not wanting gay people to have civil rights. Etc. They are standing in the way of peoples happiness and well-being. Thats why people hate Trump so much.
Ok, so you have a personal beef with him. Sorry to hear about your friends dad, but how does research help that?
