Did Americans see - and recognize - Democrats refusing to stand when Trump asked them to stand up for protecting Americans? What will they do about it

Democrats refused to stand for children who survived cancer or where permanently injured by illegal immigrants. Do those Americans mean so little that Democrats would brazenly expose themselves during the State of the Union? Do they really not give a damn? Do they really not care how bad they look? Would they have stood up if Trump asked them to stand for wetbacks? How evil can humans in power be?
