sj your logic is reversed. you are stating a chamur v kal, not a kal v chamur
if their lifestyle was much poorer than ours, so that they were NOT disgusted by things (such as an outhouse, or mud floors, etc) and we ARE disgusted by them, then how much more so should we be disgusted by things they WERE disgusted by. in other words they were MORE tolerant of disgusting things than we are.
i didnt presume you to be calling past generations ignorant, not at all.
“I dont know if there opinion holds much water today”
to me, to any Yid connected to the Mesorah, their opinions ALWAYS hold much water, and we must be exceedingly careful if we think we understand who they were, what they knew, and how they lived in their hearts, we must be exceedingly careful when we wish to deviate from what they held. (not necessarily though, the physical standards by which they lived, because nothing else was available in those times)
im sorry if we are misunderstanding each other. discussion is over for me, thank you.
