Well, the question arises of when simply disagreeing with the premises or actions of elected officials becomes "anti-government".
As a Christian, I disagree with the idea of elective abortion.
Does that make me "anti-government" if the government sanctions that procedure against my wishes?
WE, The People, right at the top of the Constitution, created this government and
granted it the limited powers to safeguard out persons, property, and rights. When it no longer serves those ends, or usurps powers not granted, it is out of line. It is no longer the government we formed. We would be opposed, and rightfully so, to any entity which took over and started acting out of line to that compact. That does not mean we are "anti-government", it just means we are for the government we agreed to, but are against that government being changed into something we did not.
Again, not anti-government, actually for OUR form of Government, and rejecting the people and agencies who would alter that without our consent.
Thus upholding and protecting our CONSTITUTION from all enemies, foreign and domestic.
If that means resisting tyranny, it is part of the package, but, again, not anti-government, just against people altering our government to unconstitutional degrees.
