Its a concept beyond them.
This is true, but I'm not writing for them...
One of the ways you influence people is to get them to ask, "Well, why do they do that?"
If you ask a question, people start trying to respond. If you give them a statement, they don't react the same way.
Slogans are good for reinforcing. Questions are good for breaking through non-thinking response.
"Why DO they act that way?" is the response I would like them to have.
If you self-identify as a liberal, these won't work, cause they are talking about that group. But if you consider yourself anything else, it is a way to get yourself considering what's going on.
