1) The inference of thread is that it not a good thing to do. The Church has ingrained a polarity with good and bad, and tradition has cemented the thinking. The words used do not imply it is the RIGHT thing to do. Take a look a Bishop Williamson's words.
"it’s not an offense against God, necessarily"
"still not a good idea"
"It’s less bad.... but it’s pretty deep"
2) The person brings up a point of history where the Catholic development of the colonies that conflicts with a quote from Bishop Williamson.
A thing need not be intrinsically sinful to be imprudent, unwise, inadvisable, or deleterious to society.
With regard to Catholic colonies, as I mentioned in my previous post, miscegenation was indeed outlawed in the French colonies. It was tolerated in the Spanish colonies because of the particular circuмstances: large numbers of Spanish men stationed in a colony thousands of miles from home, with no Spanish women to marry.
Again, the practice was tolerated for reasons of expediency. Miscegenation was by no means the norm, not even in Latin America. The fact that many, many Mexicans, and Central and South Americans, to this very day, are mostly or entirely full-blooded European, full-blooded Indian, or full-blooded negro, shows that the normal, natural tendency for people to marry their own kind naturally reasserts itself when conditions permit.
Finally, we ought to look at the current campaign to normalize and even glamorize miscegenation in the ѕуηαgσgυє of Satan's mass media. If (((they))) are so avidly for it, perhaps that might give Traditional Catholics - of all people - pause, and not accept it uncritically in the false modern spirit of "love is love?"
Heck, back a few hundred years ago they viewed the Irish as lesser evolved human.
The Irish were never not considered white, if that's what you're referring to.
When American citizenship was restricted to whites, the Irish were able to gain citizenship, and no anti-Miscegenation law anywhere in the US or Europe would have prevented an Irish person from marrying any other white person.
You're parroting a leftist narrative that was crafted to make Irish Americans more amenable to the fraudulent "civil rights movement" of the mid 20th Century, by inviting them into the Marxist fold of ennobled victims with apocryphal tales of "No Blacks, No Dogs, No Irish" signs in store windows. This myth was more or less codified in the 1995 book
How The Irish Became White, by Noel Ignatiev, a Jew (I know, shocking, right?) who openly champions the destruction of the white race, and has, as his motto: "treason to whiteness is loyalty to humanity."
This swallowing of the Jєωιѕн propaganda that floats in the ether - wholly uncritically - is really disastrous, particularly in Traditional Catholics, who have less excuse than anyone else on earth for doing it.
