Sjnyc,
What you arnt understanding is that most of the peopole you are debating here didnt reach the conclusions they have by really thinking the issues through and weighing the proofs and arguments.
They beleive what there rebbonim tell them and they beleive that there rabbonim are always right just because they do.
Even if you would show them that the facts are that there rabbonim are wrong (as was done with science issues and other issues) they would still for the most part think that there rabbonim are right no amount of arguments will change that.
