Fear based silence is a form of appeasement, which, as Churchill memorably quipped, is like feeding the crocodile in the hope he will eat you last.
Here is the thing: it will never be easier than now to speak up. If you dont speak up now and the authoritarians win, your chance is gone.
And they have LISTS. They know your social networks. They have behavioral algorithms to infer your views. They can probably do it by now from your grocery list.
They wont forgive you for silence. You cannot hide in a corner. They will find you. We have to win now or no victory will be possible.
There is no safety in anything but the victory of decency and Trump is our last best chance. I have high hopes for Michael Flynn too. They can only stop him for a little while longer.
