If I would light outside, there is a chashash that I would soon join those who do public menorah lighting. We must not do anything that resembles that new hanhoga (chodosh is ossur min hatorah), even if it means abrogating from our Rishonim and poskim.
Let them light in the town square on monstrous sized menorahs while we continue to light in the window as yidden always did. If you disagree, go to the town square for your hadlokah osa mitzvah.
Ashreinu mah tov chelkaynu, that we continue to keep our minhogim following the steps of previous doros – al titosh toras imecha.
