I should also add that when you discuss societal norms with them as this is where many will say they derive where they get their beliefs validated,
when you bring up slavery and women’s votes, they will say that sometimes societal norms are bad or wrong. One, who are they to say that, since there are no absolutes, some societal norms may just be better than others, but if there is no absolutes who are they to condemn ANY societies’ norms and customs? It may just SEEM bad to them because they may just not be the norms and customs they grew up in. They have no absolute moral belief that they can point to and say their views are superior to anyone elses.
One further point, when you get them to admit their world view really boils down to MIGHT MAKES RIGHT, them forcing their beliefs onto others,
if all societal norms are relative, and we can’t judge them as right or wrong because there is no absolute standard to judge them by,
THESE PEOPLE are trying to use THEIR own personal beliefs and norms as ABSOLUTES and trying to force everyone else to conform to their moral worldview. They are trying to impose THEIR morals (which by their own admission are only relative goods and bads) on everyone else,
so we again are led back to the question, Who put them in charge, and Who says THEIR relative morality (based in their societal norms) is superior and absolute and everyone MUST be compelled one way or another to live the way they say everyone should have to?
MIGHT MAKES RIGHT is a real crappy way to get people on board. Ones eyes must be opened first to see that this is what those crying for social justice and ‘equality of outcome’ are after.
