I would strongly disagree. Baptism isn't required for salvation. If some accepted Jesus as their savior and died in a car crash before they could be baptized, there is no theological problem with saying that they are saved.
If someone isn't baptized and rejects the idea that they need to be baptized for salvation, then there is a theological problem that is above my pay grade.
The thief on the cross is someone who died before he could be baptized, rather than someone who rejected baptism. There is no theological problem with the thief's salvation without baptism.
You don't have anything to be disagreeable about.
First, on the Cross, the Mosaic Covenant, The Law, was in effect and Jesus was fulfilling it. Why don't you read over carefully what I wrote.
