When Do We Cry Uncle?

Until when are we allowing this dangerous charade?
Asking for a friend.
We're six days into the Trump presidency and it is clear to anyone with a shred of common sense that we have a delusional maniac sitting in the White House, abetted by a bunch of irresponsible Republican flunkies and paranoid, resentful extremists like Steve Bannon. Trump rules by division, not unification, which means he is single-handedly waging war against the United States, its democracy, and its constitution. He has antagonized the C.I.A., the intelligence community, Mexico, the media, sanctuary cities, the EPA, The National Parks Service, all of science, immigrants, and even the very democratic process that got him elected.
He won yet he is still picking fights about crowds and popularity.  He is obsessed with the fact that he lost the popular vote by a considerable margin. Every single executive he signs seems to be the result of a personal vendetta. He signed the abortion gag rule the day after millions of American women marched to assert their rights.
Anybody who watched his TV interview, or any of his public appearances for that matter, can plainly see he is mentally incompetent. This condition will be exacerbated by the power he is already allowed to wield and by the public resistance that chips away at his massive insecurity, a resistance which needs to be relentless.
My question is to the Republicans who are acting as if this is a normal state of affairs. How much damage to the fabric of our system are we expected to endure? How much indignity and disrespect? How long are you prepared to look away while Trump puts this country in grave danger?
The fracas with Mexico is a serious issue. Mexico stands to be destabilized by the absurd insistence that it should pay for the stupid wall. When the Mexican economy suffers, more people cross the border. There are already walls, fences, and systems in place at the border, but Trump can only enact asinine symbolic gestures like the wall. It is not in the best interest of the US to have an unstable, economically weakened and defensive Mexico.
It is not in the best interest of the US to reopen black sites and reinstate torture. It is not in the best interest of the US to deny climate change or affordable healthcare for millions of people. I understand that Trump is only interested in feeding his own sick ego and in gaming the system as he always has. What I cannot understand is the suicidal insistence of Republicans on acting against the interests of the citizenry. Their indifference to the welfare of the American people is chilling.
