That's an utterly meaningless comparison. Bill Clinton was a governor with terrible policies concerning minorities [1], while Donald Trump was a real estate mogul with terrible policies concerning minorities. The fact that their different leadership positions meant that Trump could harm a statistically fewer number of people means exactly nothing.
"Didn't lock up any black people" isn't exactly an achievement for someone who hasn't served in government.
[1]: I agree with you that Bill Clinton deserves to be held completely accountable for his actions as Arkansas governor.
If you are talking about the cosmic tally of bad deeds, opportunity isn't relevant.
[1] Calling it "half-assed" doesn't even do it justice because the measures are far less than half of what's needed.
People prentend that politics is a purely abstract thing, but consider. Bush is directly responsible for well over 500,000 deaths. The blood of his victims is directly on the hands of everyone that voted for the idiot. Trump might not be as bad or he might start WWIII.
The alternative is actual argument rather than punishment, something overgard in no way ruled out.
...which unfortunately may not be a great tool given the current situation. I think we are at the point where playing nice may no longer be a serious option.
But that doesn't mean we should just, lke, punish all the bad people because they're bad people. That still isn't helpful. It just feels good, it doesn't necessarily accomplish anything.
In the particular case of people joining the Trump administration, I think Megan McArdle makes a good case against punishing capable people for joining it: https://www.bloomberg.com/view/articles/2016-11-09/there-s-n...
Still. We're in a situation now where argument is unlikely to get us anywhere -- but in better times, that's the ideal, not using words to punish people.
