I'm certain you are correct in that this is what he believes. I too believe that I can perhaps use my taxes more effectively for the causes that I care about rather than handing them over to the US Treasury. Of course, seeing as I don't have ownership over a slew of offshore shell corporations spanning multiple Caribbean nations and an army of legal experts at my disposal, I don't really get to make that choice.
On some level I agree with you though that there's nothing inconsistent about minimizing one's taxes and being charitable. At the same time, I'm having a hard time accepting this as an absolute truth. If the tax avoidance is a result of what some might see as a "corruption" of the democratic process, even if not necessarily illegal, I can understand why this might be considered ethically ambiguous.
