Tannaim like rebbe tarfon held lehalacha not to execute people. It wasn’t a social issue, that’s haskalah zechariah frankel baloney. Learn sugyos, like rav Hirsch said, from the Torahs own perspective. Drop the academics. Learn meforshim, and you’ll have an idea of how torah works.
Alexandria – huh? Own rules? Hefkerus? Source again, and if some jews go against the Torah it doesn’t mean that it’s ok.
