This is bad?
No, not at all. For a people who reject the idea of priests and confession, the Baptismal moment is the seminal moment in their faith journey. To feel the need to be re-newed by repeating the ritual when the faith has been lagging and needs to be re-committed to seems only logical.
I, too, was once under the impression that all Baptists got baptised frequently. Not every week, but maybe once a year.

Don't let them trick you. Most baptists do this daily, but it is mandatory at least once a week before the sun sets on Saturday, (whether you need it or not).
