The Republican candidate is a crass man devoid of manners.
"For people will be lovers of self, lovers of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy, heartless, unappeasable, slanderous, without self-control, brutal, not loving good, treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, having the appearance of godliness, but denying its power. Avoid such people." (2 Timothy 3:2-5)
If you think Trump (and the modern Republican party which cheers him on) even remotely fits Biblical principles I suggest you read your Bible again...
