Trump is more performance artist than zealot. But he's finding enemies everywhere, whether they are judges of Mexican ancestry, parents of those killed in war, the former president, or children of immigrants. Whether or not he has a sense of decency, he is in grave danger of losing it.
Aspire to decency. Practice civility toward one another. Admire and emulate ethical behavior wherever you find it. Apply a rigid standard of morality to your lives; and if, periodically, you fail as you surely will adjust your lives, not the standards.
