Very bad idea to criminalize thought, regardless of its wretchedness. Speech that is unpopular is what needs to be protected, otherwise popular speech doesn't generally need the protection. But Tim Lynch at Cato makes another point: Yep. When Canada enacted similar laws against sexual harassment at the instigation of Catherine MacKinnon and Andrea Dworkin they first when against pro-lesbian publications. This is ironic since the late Dworkin was herself a lesbian, considering all sex between men and women to be rape, regardless of consent. She borrowed heavily from Marx, as feminists are wont to do, concoting the notion that men had all the power and women aren't able to give true consent.
