Yes when one is baptized they are made a member of the Church but once they grow up and accept a heretical religion they are no longer part of the Carholic Church
http://www.catholic.com/quickquestions/what-is-the-relationship-between-the-church-and-baptized-protestantsValidly baptized Protestants are regarded as true Christian brothers and sisters who are in imperfect relationship with the Church. The nature of the imperfections is as varied as Protestantism itself. The idea at work here is that the faith is an incarnational thing, not just a “spiritual” (disembodied) thing—just like Jesus himself. Thus, it is possible to be out of union with the Church “bodily” (structurally, sacramentally, liturgically), yet still have a spiritual unity with the Church.
Maybe you’ll find the apologists at catholic.com more credible than me.
I’ll look for a more comprehensive source for you (and so I can keep it on hand for future reference), but this was the first thing I came across with a quick search.
