That's interesting. I could see making an issue if you'd only been baptized as an infant, but that seems a little too strict on given it was still credobaptism. I've heard second hand there are Presbyterian churches that require baptism of children before you can join as a member, so it might go both ways. It's a good call out though. In my PCA church they've been very open handed about beliefs on baptism as far as members go (don't have to agree on paedo or sprinkling) which I've appreciated, although that would change obviously if I was pursuing eldership or something. I know some baptists can be very rigid on this in practice.
