The Republicans almost never make any real advances on any of the social issues. During my lifetime, Reagan, the Bushes, and Trump did little more than throw bones to us pro-lifers. In exchange for this, they got us into stupid wars promoting liberal-masonic values around the world. Trump is not Christ, nor does he come even close to acting in his likeness. I do not think a protest vote for Yang is on the same level as voting for Judas.
Personally speaking, I would not vote in the general election for a candidate like Yang who supports abortion, infanticide, and the homosexual-transgender agenda. However, I might be inclined to abstain if the election were between Yang and Trump.
