Ok, so how do you do this with the Klan? How do you do this with Focus on the Family? How do you do it with Scientology?
The idea that money will take of everything is a failed neo-Liberal concept. Terrible companies and people have no shortage of money while those working towards good causes have to make calls for donations.
No, you don't do it by spending or not spending (despite Milton's claim spending money is not Democracy) but by actually challenging things. Such as, I am willing to wager Daryl Davis has pulled more people out of the Klan by talking to them than all his critics combined. Myself, I'm prone to Socratic questioning or an upfront verbal assault. There's lots of ways to do, but it does require interacting with people.
