***Maybe we could have some sectarian violence of Sprinklers vs. Dunkers with bombs and guns....***
But only if the dunkers do it in the right method,forward or backward, the right number of times, the right name or names and only in the right frame of mind at the time of dunking.;-)
One bit of symbolism in baptism by immersion is that when we breath in Bible doctrine on the inhale, the Holy Spirit immerses us prior to us breathing out epignosis on the exhale through our heart. Insofar as we might be manifesting our admittance of His work in us, this might provide additional testimony of His work.
I suspect any type of baptism would satisfy the command.
