For example, obvioiusly most who oppose homosexuality on "moral reasons".....oppose the legalization of same-sex marriages. But ask them this.... "If you truly oppose homosexuality on moral grounds...and you want our legal/governmental system to ban homosexuals from marrying one another due to that moral objection......would you also support a law that made it illegal for a man to kiss another man or a woman kissing another woman?" I'd love to find one who would say "Yes"...but haven't so far, which means there is a "limit" even to their distain and wish to use the law to enforce their views. That in itself shows a potential for "evolution" on their part.
