Ya'll need to get your ducks in a row on this issue....among others.
Convert Catholics typically were baptized under the auspices of some other Christian community (e.g. Baptist) before they were received into the Church by Confirmation, but their previous baptism is recognized as valid: they are not re-baptized.
Those ducks are in a row!
However, ex-Catholics, post-Catholics and anti-Catholics are not allowed to post in the Catholic Caucus, although it can get dicey because some people, like yourself, are not very forthcoming about what "faith community" they are actually part of.
