I see your point, but Nazi Germany strengthened the laws against homosexuality (which then remained officially on the books until the late 1960s), and considered homosexuality a violent sexual crime against nature and against the State. Every man and woman was expected to make babies for the Fatherland.
So I think Mr. Wilde us saying that, since anyone can check out the sex offender registry, and since some elements of the media warn darkly that registered sex offenders may live in your neighborhood (oh, my!), it serves as a digital "scarlet letter", equivalent to having to wear a pink triangle.
