I really thought this was a fairly simple question.
Another thing, I'm glad I grew up in the Baptist church that I grew up in. We were never taught that Catholics are going to hell. I'm not sure why what the number birthday you were saved on matters. I never heard of these things. The holy rollers were looked at as not being all there, as were/are the snake handlers, but if they have a personal relationship with God, and they have accepted Jesus then they are saved.
As far as Catholics, we just were of the opinion that praying to other people then Jesus borders on idol worship. We also have an issue with confessing to a mortal man, who really doesn't have the power to forgive you of your sins. Then there is the issue with the Crucifix. Baptist see it as Jesus still on the cross. We wear a cross that is empty because Jesus was taken down, and placed in the tomb, then as we all know he rose 3 days later, and ascended to haven 40 days after that.
Anyway I'm thinking that the answer to the OP is that Muslims are actually Islamist. So, now that leads to the question, are all Islamist, Muslims? Like Christianity has different denominations is it the same for Islam?
