There is even a bill pending in the House (H.R. 2631, called the Religious Freedom Peace Tax Fund)which would allow war protesters to direct the war appropriation portion of their taxes to other areas, but it appears to be based solely on religious objections to war, per se.
What percentage of our taxes goes to fund Congressional salaries/pensions/benefits? What percentage is already, by law, allocated for border security, but remains unappropriated/undisbursed? How many of us would it take to make IRS enforcement burdensome? A penalty escrow account would cover the penalties levied. If this sort of action was accompanied by direct action such as: affixing prominent, difficult to remove stickers to any building owned by employers of illegals/products of these employers that appear in stores, permanent paid pickets (just like the donks use) against any company that employs illegals or any retailer selling those products,sit ins and other civil disobedience against anyone facilitating illegals, including Congressional committee hearings (again: just as the donks do to get media attention), and whatever else anyone can think of to make it perfectly clear that we the people run America, not the corrupt politicians.
Couple this with a commitment to live as frugally as possible so as not to even owe any tax, legally, and we would perhaps be able to thwart the elites without resorting to other, more serious, direct action. I frankly doubt the resolve of most conservatives to even consider revolution of the armed sort and having lived under martial law in Milwaukee in 1968, I would also be afraid to engage with the Guard under those circumstances.
Otherwise, I fear that most of the venting on these threads is just that and will amount to nothing concrete, ever.
