Ah yes, surely the meaning of that bible verse is, "Don't ask mildly difficult questions based in any sort of moral stance." Because we all know that book is famously opposed to performing any sort of moral analysis.
There's asking questions about the circumstances to better understand before casting judgement, and then there's sarcastically implying that OP is a bad parent for endangering their child without asking any actual questions about what happened.
That was not sarcasm, which generally requires words used in contradiction to the normal meaning. E.g., if somebody makes a dumb mistake, the response, "nice work, Einstein" would be sarcastic. This was at worst mocking, but it wasn't ever hyperbolic, given that the what was written was a literal description of what the guy did.
Regardless, you haven't answered the point about the quote. "Judge not lest ye be judged" does not mean we have to empty-headedly refrain from any sort of moral criticism. In context, it's about hypocrisy, reminding us to apply our standards to ourselves as stringently as we do others. I think it's only appropriate here if tsigo somehow indicated he would happily endanger his own children, which I don't see any sign of.
