Personally, I hope they won’t “go high” this time. I ordinarily think we should do better, be the example, in life, but there’s a time when you must show your limits when it comes to such cruelty and ugliness.
It’s good to not bite at first, and to try and reason as much as you can, but when it comes to hate and greed (racism, corruption, disregard of democracy, etc etc etc) show no mercy.
Any kind of mercy will be seen as weakness with these types, and in four years, trump may be gone but they will try and place someone much more sly to take advantage of trumpists leftover and it will be that much harder to beat them.
