>Baptism of Water EXISTS for deathbed!
>Therefore Baptism of Desire DOESN'T EXIST!!
Come on. The logic is so poor. 

OP actually laid out the point, which you distort because ... you can't understand it or you don't care for EENS dogma.
This is another example vindicating Fr. Feeney (RIP):
"There is no one about to die in the state of justification whom God cannot secure Baptism for, and indeed, Baptism of Water. The schemes concerning salvation, I leave to the sceptics. The clear truths of salvation, I am preaching to you."
Since you evidently needed just a little help understanding the point.
So, these are examples of where God provided Baptism "against all odds" and even miraculously, to reinforce the point that God cannot be thwarted by any kind of "impossibility".
Also, the fact that God went to such great lengths to provide Baptism for those who by most account should have been saved by BoD anyway reinforces its absolute necessity.
So the point is, if God does not NEED to provide a "Baptism of Desire" to save His elect, they why would He will for some to be saved by it?
Thank you for your attention to this matter.
