We each have our own standards about which words and deeds are forgivable and which are not.
For me, Donald Trump’s failure to halt the assault on the Capitol last January 6th was unforgivable. I voted for him twice. I will never vote for him again.
For me, Kamala Harris’s comparison of January 6th to the Japanese attack on Pearl Harbor, that killed 2,400 Americans, and to the al Qaeda attack on 9/11, that killed 3,000 Americans, was inapposite and inappropriate, unforgivably so. I’ve never voted for her and I never will.
