Avira> In places where jews mingled, you only had pogroms, inquisitions, expulsions, massacres, and Holocausts
So, you are turning to a totally opposite position than UJM who sees a perfect view of earlier European Jewry (as those were the places of pogroms and Holocausts), with both of you claiming a undisputable power to peach to everyone else. Maybe you can figure out between each other, whose tradition is correct.
Also, lately, bli ayn hara, the places without pogroms include US with the tremendous assimilation happening in last 100 years and Medinat Israel, protected by Tzahal. We, of course, may notice that both places have great and growing Torah communities, but you can’t deny “mingling” also.
