I have several mottoes which concur with this.
“Issues unite, names divide”. Focus on issues. You can reach across party lines on issues. Once names are involved, all agreement is lost.
“All names are cults”. Doesn’t matter whether it is Trump, Hillary, Bernie, AOC, Gabbard, RNC, DNC, etc. People will accept atrocities as long as they are done in the name of the cult.
“We have no heroes. We are our own heroes. Act like it.”
