Referring to this article.
There is no “the” right thing under materialism and moral subjectivism. There is no “the” wrong side. Had Irish voters elected to round up and execute all gays and lesbians, under materialism and moral subjectivism that too would have been a right thing. Had they elected to lobotomize them, that too would have been a right thing, made right by that which legitimizes as right any subjective moral or ethical good under materialism: the individual, or the group, or the community, or the society, or the culture consider a thing to be good or right.
That headline corrected for logical consistency under materialism and moral subjectivism would be: “Irish Voters Do the Right Thing What I Personally Preferred. Church Was On the Wrong Side, In Disagreement With My Personal Preferences As Usual.”
Only a moral outlook where morality is guided by an absolute, objective commodity can be logically consistent with that thread headline. Theism is the only source of an absolute, objective morality. As I have said before, materialists cannot even act or argue as if materialism is true.
