SL, my point here was not to try to defend Judaism from what you perceive as my perception that zdad is attacking it. Truth is, I don’t think anybody else here believes that the keeping gebrokts is affecting anybody else in any discernible way.
My point was that even zdad himself doesn’t honestly believe the point that he was making. If he did, the argument would cut both ways. The fact that he continues to spout this argument as a reason to discontinue the minhag of gebrokts, while completely burying his head in the sand about the fact that this argument can just as easily obligate everyone to eat only non-gebrokts, shows that he himself doesn’t really believe this argument to be true.
