There are those people, and there are the people that don't know about the bad stuff. Actually, to be fair, there are also the people who know about the bad stuff but dont think lowering tax revenue is a good way to get them to stop doing the bad stuff. I think the first group of people might have a strange set of values (unless you mean that they don't think the net effect of what the government does with taxes is bad, in which case I agree with them), but it's still worth arguing about to convince the second and third groups.
