You're in your 70s and coming down with covid, the moderator asks you to tell white supremacists to "stand down". You ask the moderator who should you say that to? Biden interjects "proud boys". You try to repeat what the moderator told you but instead tell them to "stand back"/"stand by" instead of stand down.

Literally one of the people explaining how trump supports white supremacists to me made this exact same mistake despite him being in his 30s and not coming down with covid.

Trump is a terrible president for plenty of reasons, we don't need to make ones up.
