<em I heard last night at a shiur on Pesach that since our approach to kiruv has changed, the advice of the Baal Hagadah may not apply nowadays.
Whose authority is big enough to decide to change our policy from following the Tannaim to a more modern day attitude?
In the time of the Taanim, the Rabbanim had more real control over people, they could force you to keep Halacha and throwing out a Rasha, would likely lead them to Tshuva
Today if you throw out someone calling them a Rasha, will more likely lead them to leave and not come back and maybe even become “successful” and not let you forget it
