This isn't wrong, but this argument gets made over and over and over again in every political thread on almost every topic, whether or not it fits the flow of the conversation. People don't want to be preached at and it's going to be self defeating.
EDIT: Tone deaf establishment apologists are going to lose again and still not understand why. "Republicans suck more" is far less compelling than some people think, no matter how true. Winning elections and winning arguments are different things.
