in fact what I wrote is of utmost relevance, if you accept strange occurrences in your bible that are utterly demeaning to God's chosen messengers as fact, then you have no reservations whatsoever if the talmud or Mishna refer to Mary as a (.....) or her son as (.......)!
all the best
The Bible contains many factual stories and those stories do not always show the characters involved in a good light and in its own way that itself is a testimony to their verity.
If you take the view that all God's messengers are without sin then I consider that to be an absurd position to take without a shred of evidence to support it and if anything demeans God this assertion does, it puts God in a position that he somehow owes us something, we deserve his favour.
The Mishna and its supplement the Talmud records all kind of things including the traditions and no one but an idiot would assume they are all true or correct but they may well be useful to see how a religion develops and of course they help with refuting error. They are not unlike your hadith which also contain to my mind very odd not to say fanciful stories, the Qu'ran itself has strange stories as well such as the cave or such things as Prophet Mohammed's heart being removed and washed with snow - in short I cannot see you are making any valid point and so far what you say has zero relevance
