The Constitution is an agreed upon framework of rights and laws in this country. If the executive branch fails to uphold any part of it, you do not have an individual responsibility to follow it. "President" trump has violated the emoluments clause, and should have been impeached immediately. He is attacking birthright citizenship, ignoring court orders, including orders from the Supreme Court. It is the literal definition of unconstitutional.
At this point the law in America is : Do whatever the fuck you want, as long as you have the guns and propensity for violence to back it up. Most people just haven't realized it yet. The only way out is for Congress to swiftly (hah) impeach Trump (hah again), put his ass in jail (hah x3) before people start shooting. We may already be too late. This charade has gone on too long.
