Political correctness is for Progressives, Leftists, Fabianists, etc. what 'morality' is as it evolves over time. And because only Leftists et al possess the gnosis of evolved 'morality' only they know what right and wrong is at any time.
Our nation was not founded on Leftism and evolution but on Biblical concepts. Of these, the existence of an eternally unchanging, personal Tri-Personal creator God who created persons (not evolved entities) and only two sexes, male and female, is the foundation stone of our unalienable Constitutional rights. Likewise, His unchanging moral law is the transcendent source of our morality.
In this light, a vote for a 'gay' is by default a vote against America's founding worldview and for Leftism and evolution (change).
A person who embodies nothing but identity politics is no one I would vote for.
We’re not defined by our external identity but by the content of our character and how we live in our lives.
What we do matters a lot more than whether we’re a member of this or that tribal group. Period.
Conservatives want a society of decent people not a collection of politically correct victim groups.
