Posting 1 incident in the non frum world proves absolutely nothing.
i dont have any fancy articles to show u, but i live here and find myself day to day going back and forth btwn religious and non religious neighborhoods.
the non religious are מצפצף on all the rules just as bad as the religious, if not worse.
on יום העצמעות during the lockdown, i drove thru the מודיעין area, and the parks were full of unmasked חילונים making barbeques
