Regarding this controversy, Trudeau did a few things of note:
1. He admitted that he did it.
2. He admitted that it was wrong.
3. He accepted complete responsibility.
4. He explained in detail why he now understands what he did was wrong.
5. He sought forgiveness.
Difficult steps for habitual Trump defenders to comprehend, but this is how politicians (or anyone, frankly) can seek forgiveness, if they’re looking for it.
