You don't hear anyone complaining about cleaning up American cities to get drug dealers, prostitutes, and gang members off the streets. And no one complained when Exxon had to clean up after the Valdez oil spill. Use labels rather than explaining. Many readers will not think to question whether a label is truthful or fair. Attack your opponent, not his argument.
Readers find it hard to distinguish between the two.
Our opponent believes we should spend more on education. In fact, there's evidence that he beats his wife and drinks too much. He also has a history of unpaid traffic tickets. Feel free to confuse what is with what ought to be. You'll trip up readers who aren't sure about the difference.
