They say
Luke 23:43 — saved without baptism, so baptism is optional.
Luke never says he was unbaptized. That is their insert. Mark 1:5: all Judea and Jerusalem were baptized of John. He called Jesus Lord and knew He had a kingdom. Scriptural Mormonism: who can really say he skipped it? Jesus Himself was baptized — then they crucified Him as a criminal too.
Mark 1:4–5
KJV · John did baptize in the wilderness… And there went out unto him all the land of Judaea, and they of Jerusalem, and were all baptized of him in the river of Jordan.
NRSVUE · John the baptizer appeared in the wilderness… And the people from the whole Judean countryside and all the people of Jerusalem were going out to him and were baptized by him in the River Jordan.
Luke 7:29–30
KJV · All the people… being baptized with the baptism of John. But the Pharisees and lawyers rejected the counsel of God… being not baptized of him.
NRSVUE · All the people who heard this… having been baptized with John’s baptism. But by refusing to be baptized by him, the Pharisees and the lawyers rejected God’s purpose for themselves.
