Straw-man argument. God did not say, “White-skin folk shalt not marry Brown-skin folk.” That was a fake construct of American racism (by politicians for whom more than a few were having their own white-on-brown affairs on the side). He was thoroughly clear on His position on homosexuality.
You are absolutely correct. Nobody ever argued against inter-racial marriage on the grounds of marriage’s definition, because its definition never made any mention of race, stretching all the way back to the Bible. The arguments that were used were based on racial purity and supremacy. This is fundamentally different.
You cannot alter the definition of marriage because its not a human concept. It’s a concept from beyond this world, given to us by our creator, and its the same whichever religion you are talking about, and let me say this...
Other religions outside of so-called ‘Christian’ society will never accept it. The Muslims sure as hell won’t recognize it. Hinduism - “Premarital and extramarital sex are wrong, and because homosexuals CANNOT MARRY, they should not engage in sexual relationships.”
We could even mention the Amish community. Are they ‘bigots’? What an outrageous assertion. According to these people, the majority of individuals on this earth are bigots, and bigotry is some sort of transient concept that changes which indicates if pedophilia became acceptable in our society (and that’s not ridiculous because it has become acceptable in a few societies), those against it would be the new bigots.
The word ‘bigot’ is becoming the new ‘racist’. A word thrown around so often, its lost all meaning anyway. Essentially, anyone who disagrees with me is a bigot.
