Stay informed. Be honest. Exercise your First Amendment rights.
And love each other like there's no tomorrow.
The First Amendment to the U.S. Constitution prohibits the making of any law establishing a religion (even Christianity), ensuring that there is no prohibition on the practice if any religion (even Islam), abridging the freedom of speech (even criticism of Trump), infringing on the freedom of the press (even the NY Times), interfering with the right to peaceably assemble (even Black Lives Matter protesters), or prohibiting the petitioning for a governmental redress of grievances.
Stay informed. Read the real news of what actually is happening. Support real journalism and join or subscribe to The Guardian and The New York Times (I did both last weekend). Check the references of any news story that presents an outrageous, one-sided view, even if it's posted here.
Be honest. Tell others what you know, based on your staying informed. Don't spread false rumors and don't mistake what you wish were true, what sounds "truthy," with what actually is.
You do those two things are you're well on your way to exercising your First Amendment rights.
All that's left then is loving each other.
