Civility is very important, but it is not of the utmost importance. I'm being pedantic, but not in the linguistic sense; when you're faced with existential threats or severe attacks upon one's moral principles, then it's appropriate and sometimes even necessary to express anger.
Suppose, for examples, that the allegations swirling around DC these days are well-founded and the administration has been lured or willingly entered into being co-opted by a hostile foreign foreign power. For all the jokes over glowing orbs and handshakes, there's a strong argument that the post WW2 international political consensus is under deliberate attack designed to create strategic instability.
If you're a student of history, this is deeply worrying, and there's a small but realistic chance of the US sliding into autocracy and a similar chance of a third world war breaking out in the coming years. Not every conflict can be solved by polite engagement and mutual understanding. If you are dealing with a bad actor who does not subscribe to your moral calculus, then putting civility above all else can mean putting yourself at a significant strategic disadvantage.
surely you are aware of the increase in racially and politically motivated violence across the country. I can readily direct you to prominent political figures with significant public followings who are openly advocating ethnic genocide within the US; nazis, to put it bluntly. IT is facile and dangerous to sugarcoat things for the sake of preserving a superficial tranquility.
I'm not defending the crude comment above, but asking you to take a little time out to evaluate your political norms and mores while you have the space in which to do so, lest you find yourself taken by surprise by future events.
