Mind you, these are 'utah' Mormons - so they may be kinda different.
I was thinking that just as I read this.
Yes, Utah Mormons tend to be a "different" variety of LDS. It seems to be primarily social for them. If they do not care about the theological arguments against it, it might be because they really don't care about theology at all. It is all about getting along with their social group.
But as one who has experienced the Church outside of Utah and in three different countries, I sense things are a bit different. If I wanted to I could probably single-handidly reduce LDS membership in our stake by half, just by catching everyone by surprise the next time I am asked to speak at a fireside (which I am frequently called to do). And I wouldn't even really have to start attacking the Church. All I would have to do is talk about the controversial issues in a round-about way as if I expect the audience to already know about them. Perhaps by sharing my experiences with some anti-Mormons online who criticize the Church for its blacks/priesthood policy. I can pretty much tell you that the majority of Brasilian Mormons have no earthly idea what this is about. Of course none of this would work in Utah because the membership is mostly white and they have been, to some extent, apologetically immunized from concern over the more obvious controversial matters.
However, virtually all Brasilians in Brasilia are related to someone who is negro and they are unfamiliar with all LDS apologetics. They would not put up with it. They would not be inclined to rationalize it all away with a ""the Church is still true" attitude. They would probably be more upset with the fact that nobody ever told them about it.
As Kevin Barney rightfully put it, to baptize someone without teaching them about this old policy, is nothing short of "missionary malpractice." And this is especialy true for those who are probably related to someone who is black.
