@KeepTakingTheSoma @sim @HebrideanHecate I think perception does change. Just look at how homosexuality was dealt with in the first half of the 1900s, even in the 60s and 70s. Electroshock treatments, conversion therapy through coercive and forced sex with the opposite sex, psychiatric institutions (my mother once threatened to have me institutionalized), the insults and name-calling, homosexuality meant perversion, lesbians lost the right to raise their child if they had comp-het relationships before coming to accept themselves, and the rest. Now I'm sure some people still hold those beliefs against gays, bisexuals and lesbians, but they know they are outnumbered so they keep quiet.
Another example. Women having children out of wedlock and so on.
