Unitarian Sharing Circle: Dilemma

This year I owed the U.S. government a good amount of money on my federal tax return. I had suspected I might owe because I’d received a lump payment from Social Security that was for an entire previous year. I was angry. Angry because of the actions of ICE, because of the war the U.S. had started with Iran, and because of poverty in America. I didn’t want to pay for this needless cruelty. Briefly I considered refusing to pay, but I was afraid and wrote the check. Should I have stood up and refused to pay? Would it have done any good?  I thought of Thoreau and his refusal to pay his poll tax resulting in his night in jail for this refusal. Am I a coward? I am not sure but I am still evaluating my choice. Are there any decisions or choices you have made that you still think of and wonder what you might have done differently?
