There is room for disagreement on immigration policy.
As a staunch agonist, I honor even extreme, bitter conflict on such issues.
Those who disagree with current policy have every right to protest it publicly.
There should be less room around enforcement of current policy. Policies are designed to narrow possibilities into practical particulars of enforcement.
Protesting policy by actively interfering with its enforcement is a dangerous line to cross, if we wish to preserve rule of law, which is a fundamental precondition of liberal democracy.
But enforcement outside the bounds of policy is at least equally dangerous, and repugnant to any decent citizen of a liberal democracy.
Civil rights are non-negotiable and sacred.
This is why I have donated to the Red Card Campaign, and why I think every decent American liberal or conservative, ought to donate, too.
I am compelled to letterpress print Red Cards. All sacred ideas call me to the press.
