I was thinking more along the lines of not being too harsh on those with more 'traditional values'. Like our Muslim neighbours, or those who think women should stay at home, or maybe are uncomfortable with modern ideas of gender and sexuality.
Not sure I'd throw in paedophilia (since minors are unable to legally consent to sex with adults), or bestiality (animals definitely can't consent to that), or incest (if it results in a child it can have severe consequences for said child).
Regardless, while it's great that we now recognize people of other races are equal (at least nominally), we shouldn't be too smug when denouncing others who aren't as 'progressive' as we are (see all the propaganda regarding homosexuality in Russia - where it's actually legal; versus India where same sex relations are illegal).
