Coulter cites statistics when she talks about negative outcomes of single motherhood. If you love children you should discourage people from doing things that contribute to poorer life outcomes for them. That's offensive to some people so the facts about it don't get out. She sheds light on it.
Furthermore you don't seem to understand that an argument cannot rest solely on facts. Facts are CRITICAL to 'winning' the debate or pushing forward your perspective however if it is just dry facts you will have no audience. Humor, interesting stories, personalizing the situation with the audience are all things people do to get and then maintain attention. I've read the Road to Serfdom and I've read Coulter, Hayek is boring as shit even though I pretty much agree with his ideas. How you present information is massively important. The idea that college shouldn't talk about the very real way people discuss and promote ideas is absurd. Academia should prepare people for the real world, and in the real world that is a big deal.
