Comparing Liberals views about sex and guns: Why do they support training for sex but not guns?

Charles Cooke raises an interesting question about the distinction about what liberals think should be thought about.  From his piece in NRO:

. . . The New York Daily News remains censorious. Lambasting the event’s “Youth Day,” which featured an air-gun range at which children could compete to win multicolored marksmanship ribbons, the paper printed a series of pictures of children holding firearms. The captions read “SCARY SIGHT,” “FRIGHTENING,” and “SICK!” 

Subtle the Daily News is not. Bill Hutchinson, author of the piece, complained that “some of the attendees were the age of the Newtown massacre victims, others too young to know the difference between a toy gun and a real one.” 

This is astonishingly dishonest. How, pray, are children supposed to “know the difference between a toy gun and a real one” if they aren’t shown that difference? And what better way could there be of showing them that difference than to offer them instruction from a professional, as the NRA did, or — even better — having conscientious parents who are open about it? Love them or hate them, guns do exist — there are 360 million of them in the United States. Are we to pretend that this is not true? . . .
