Leftists and Republican Trump-haters together are practicing ageism by collectively pretending that it's Biden's age and not his mental disease at issue. I know many people much older than Biden quite capable of creativity and working for a living.
This hard bigotry of ageism is going to rebound and bite these Trump-haters and leftists on the butt because they, too, will eventually age out of social or cultural viability, and begin to be treated with contempt due to their wrinkles. It's just a matter . . . of . . . time.
