My experience has been that if you say anything at all perceived as "opposing," they'll label you an apostate whether you were ever baptized or not. Mere "opposers" are those who never were in "the Truth."
I was never baptized, left as soon as I was of age. My mother once said she considered me "worse than an opposer" because I supposedly "knew the Truth" (having been raised right) and chose to leave it. And so many others in the congregation took the same tack that at one point I had to inform a peer that, not only was I NOT disfellowshipped, I'd never even been baptized. He assumed that, because I was being shunned, I was disfellowshipped.
Of course, after years of keeping my mouth shut about JWs (can you see the scars on my tongue from biting it?), I now get treated just like any other old worldly person. I guess my mother thinks I've forgotten all the stuff she taught me, because from time to time she feels it necessary to "explain" her religious beliefs. Perhaps she thinks I inherited the short attention span that the WTS has inculcated in her over the years (and don't ya know, I've gotta be a former JW kid if I use words like "inculcate"!).
