Nicholas Stix at the VDARE blog has a good point.
Every single argument that is used against immigration enforcement can also be used against paying income taxes. Likewise, people who seem to insist that deportation should be treated under criminal justice presumptions rather than civil ones (that is, that people should be considered legally here until they are proven illegal) never seem to put the same thinking into filing out individual income tax forms.
While I do not advocate "tax striking" it does seem to me that as a thought experiment it provides a good counterpoint to those who demand amnesty for illegal aliens, and reveals their hypocrisy when they couch their terms in the impossibility of enforcement or in the unconstitutionality of effective enforcement.
That is all.
