Are you talking about Kavanaugh? If so, there is a noticeable difference between the two issues..... Kavanaugh was accused of rape, a crime. Northam is being accused of nothing. It may be deplorable, but it is not illegal to dress in poor taste for a costume party.
And like with Kavanaugh, I'm not saying this should be ignored in regards to Northam's next re-election campaign or job search. I know he wouldn't get my vote, but my vote/opinion isn't the only one that matters. And beyond that, what good does it serve for him to step down this week? Exactly what justice is being served when no crime was committed (30 years ago)?
Anyone who voted for or defended Hillary does have that opinion, they may just be naive enough to not realize it, but what difference does that make at this point anyway? Anyone who's ever enjoyed a Jimmy Kimmel joke holds that opinion. Anyone who's ever watched a Notre Dame football game with Chip Kelly as the coach holds that opinion. I could go on to varying degrees of social offenses..... Those folks have all committed equal or far worse offenses, yet are still media darlings, or at the very least, not trashed by the media and social mob. Why Northam in regards to blackface, but not Kimmel? Why blackface, rather than covering up for your husbands predation of young interns? Why a poor taste in costume, but not actions that lead to a kids death, like with Kelly and Clinton?
Criticize Northam all you want, but if the new standard is that people who've made a dumb joke or worn a deplorable costume need to be fired or step-down, then we're screwed as a society.
