Common sense dictates that you get more flies with honey than with vinegar. Whether or not you agree we deserve such respect, it would certainly be more persuasive than labeling all of us as deplorable bigoted rubes. But, please feel free to keep on making the same mistakes that cost liberals their traditional base to begin with.
Right, but you have no problem with conservatives voting for a sexist, bigot who routinely insulted and villified women and minorities because he didn't refer to anybody as 'deplorable'?
The thing is, I'm not trying to win your vote.
You are going to have to win some fraction of Trump voters' votes if you want an electoral victory.
I would certainly give the same advice to conservatives if counseling them on how to persuade members of the other side, but given that they won most recently, they seem less in need of such advice.
Not at all winning back most Stein/Johnson voters is more likely/easier path to winning in 2018/2020 an that can be down by running a more liberal message which Trump is actually making easier by bringing back the war on drugs and pulling out of Paris
