It is a truism that it’s much easier to discriminate against a class of people whom you have never met. Justice Powell, prior to ruling in support of an anti-sodomy law, is famously said to have remarked that he didn’t believe he knew any homosexuals, not realizing that his very own law clerk was gay‚ but still in the closet. This issue was a large part of the rationale behind encouraging gays to come out publicly, and it is behind the nascent movement encouraging women to talk about their abortions ( http://abortionandlife.com/ ).
