Are you suggesting that he's, er, too old to be punished?

FFS, Steve, of course not. But Yarrow WAS punished for what he did 50 years ago 50 years ago. And he freely admitted what he did. And he apologized - repeatedly- for doing it. And he's done a world of good since in various spheres of humanitarian activism. Should we "forget what he did"? Of course not. Neither should he continue to be punished and persecuted.

it doesn't follow that they treat every offence as equivalent and equal.

Ah, but they HAVE done & continue to do so. Its well documented - check it out. Start, e.g., with the aforementioned Al Franken. Or Garrison Keillor.

Again, when do you figure the Me Too true believers will get around to the serial rapist in the White House?
