Cards that CAN and CANNOT be soaked?!

[yanks87]

I am going to preface my statement by saying that I understand the difference between the card scandals running rampant in the high grade cards currently and this, but I still have an issue how this thread is so openly accepted and people who trim, recolor, or alter cards are blasted. If the card is staying in your collection, you can do whatever you want to it, the gray area comes in when the intent is to resell the card. Soaking cards compromises the genuine integrity of the card for one benefit, to remove part of it's story to increase the value. Apples to apples with pressing, trimming and recoloring. In a truly benign question, can someone explain how this is any different than a non-acceptable method of card alteration?
