It is your right to believe that, but the practice is wrong according to SB theology. You have to agree with their theology or find another denomination. That doesn't seem unreasonable to me. To people who think this isn't of God, that leaves them wondering the source of it. You must see why that's a problem for them.
This guy just sat back down and went to the pastor the next day with this question: "I don't believe this woman was demonic, but she clearly spoke in error in the name of God, in first person. They stoned people to death for this in the Old Testament. How do you distinguish between people who "truly" have a gift of interpreting tongues and people just worked up and they want to believe something?" My friend did nto believe there was a "truly" gift at all. He just was non-hostile, gentle, and willing to win the man rather than the argument.
