“Why does abortion matter so much to the Yanks? It doesn’t matter to us! It’s no big deal! Why the violence associated with a violent action?”
That said, the statistics they quote of violence by anti-abortion protesters are more than I’ve ever heard of, but I’d like to see a source other than the National Abortion Federation.
But it doesn’t really give one the moral high ground to make the argument that the UK is better because they don’t think abortion is as serious an issue as Americans do, or that the “problem” is that Americans are more religious than Brits.
