It is not a question of “revoking” anybody’s baptism. The LDS Church does not “revoke” anybody’s baptism. Baptism is the gateway for entrance into the kingdom of God here on earth (and ultimately in heaven). It is the door by which one enters into His Church. When somebody leaves the Church, or is excommunicated, that means that he is no longer in it; and the only way that he can get back in is by the same door that he left, which is baptism. There is no “backdoor” by which he can enter in.
Christ never explained baptism in this manner. There was no “leaving”, only repentance.
Then you must have even bigger problem with your eyes than I thought! If it “doesn’t matter,” why do Catholic posters bring it up, and try to use it to bash the LDS Church? I entirely agree that, ultimately, it “doesn’t matter”. But like it or not, this is a place where people like to exchange their opinions about religion; and this is a subject that has come up in the past, and no doubt will come up again in the future, and therefore needs to be addressed.
I have seen debate. I have seen questions. I have seen statements that are from a very definitive Catholic POV, but hello, this is a Catholic forum. I have not seen anything that would be bashing.
Another way that it “matters” is purely as an academic exercise. It matters in the same way that history matters. Just as it is good to study history to learn the truth about the past; it is also good to study these things to learn the truth about them, and not rely on somebody’s guesswork or half-truths (or untruths).
Ah yes, then you should take your own advise and study and learn the truth.
I believe no such thing. After all, we don’t recognize their baptisms, so why should they recognize ours? What is significant, and you should bear in mind, and not forget, if that is not too much to expect, is that
we refused acknowledge their baptism
looooong before they refused to acknowledge ours!

That is the main difference. Our position is consistent; there is not!
I am well aware of the exclusionary nature of mormonism.
It has been explained to you why the Catholic church does not recognize a mormon baptism. To boil it down…Mormonism is such a fringe religion the Vatican considered them the same as any other protestant religion. You and I know that is not the truth. When the Vatican was made aware of the differences in baptisms, they realized that a mormon baptism does not meet the definition as you can read in the Catholic catechism. The Catholic church did not change, their understanding of what a mormon baptism is (or rather is not) did.
