How do we know the OP had any issues coming up with valuable and insightful comments? Tone can have an impact - being particularly rude is not likely to result in good outcomes (but maybe it could in some situations). Why aren't we exploring what was originally asked?
Because all of the versions have the same problem regardless of tone. If the assumptions are in error and the OP had been leaving off the justifications suggested, they can reply and say so! (But, as it turns out, didn’t.)
