Then you have a contradiction within Scripture, which does NOT exist if baptism is NOT a condition for salvation.
So, explain the contradiction of this passage where there is no mention of baptism.
Romans 10: 5-17 5For Moses writes about the righteousness that is based on the law, that the person who does the commandments shall live by them. 6But the righteousness based on faith says, "Do not say in your heart, 'Who will ascend into heaven?'" (that is, to bring Christ down) 7or "'Who will descend into the abyss?'" (that is, to bring Christ up from the dead).
8But what does it say? "The word is near you, in your mouth and in your heart" (that is, the word of faith that we proclaim); 9because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. 10For with the heart one believes and is justified, and with the mouth one confesses and is saved. 11For the Scripture says, "Everyone who believes in him will not be put to shame." 12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. 13For "everyone who calls on the name of the Lord will be saved."
14How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching? 15And how are they to preach unless they are sent? As it is written, "How beautiful are the feet of those who preach the good news!" 16But they have not all obeyed the gospel. For Isaiah says, "Lord, who has believed what he has heard from us?" 17So faith comes from hearing, and hearing through the word of Christ.
The irony of all the Catholic railing about baptism being necessary for salvation, is that even if one believes that to be the case, I don't know a Christian who has not been baptized at some point in their lives. I was infant baptized into the Catholic church.
So we're good to go anyway......

When I was in Indiana in the midst of a bunch of small non denominational churches, a great deal of them were not baptized, or were baptized as more mature adults.
Well, let us see what else the Bible says about baptism. You argue from the point that certain conditions are required for salvation. We agree that they are there. What else is there?
John 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
Mark 16:16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
Acts 2:38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
Luke 3:3-4 And he came into all the country about Jordan, preaching the baptism of repentance for the remission of sins.
Looks like we have an "and" going here. Unless you take Jesus and John the Baptist off the ticket entirely.
