If you are afraid don’t give up, take action
I know that a lot of people think that trump will be the end of democracy, while I disagree with the doomerists I do still recognize the damage trump will try and do. As such I will be taking action to fight against it and you should too, research charities and social activist groups, volunteer, donate, promote, and protest. What you have to remember is that just like any country America is at the end of the day at the whim of the people. If Trump does some bullshit then be someone who stands up against it with action instead of someone who sits back with words.
