Earlier quoted context omitted.
I hope you are referring to the men and not Ms. Richards. Because her "little mistake" resulted in the firing of a decent human being with a wife and 3 kids.
She posted a tweet. Even had she called for his resignation (which she didn't), she didn't have any power to effect it. What about the overreacting HR people who actually fired him over that tweet (knowing about the 3 kids and all)?
This was a pretty scary scene she perpetrated, at least to me. You can really do damage to someone with a mere tweet. Over a dumb, overheard joke? Come on. Judging by the public sentiment, it'll probably be okay for this guy. He's been incredibly gracious publicly. But had he gone home and hung himself, what story would we be talking about?
