Talmid, since you chose a town where that actually does hold true, you do have a point. A person is not always going to be able to earn a parnasah in a tzniusdik place. Tons of Jews work in Manhattan, surrounded by goyim, and life goes on.
I don’t think that negates the OP’s point, however. I believe he wanted to make a post about a problem in the 5 Towns, but he rephrased it as a personal problem, which was smart. If you phrase something as a societal critique, then people will call you a troll and say you’re an extremist up on a soap box. Rephrasing it a personal issue makes it much more likely to get past moderation and be treated with respect by other posters.
As for the merit of talking about it at all, it would be pointless to make the point about Harlem where everyone is goyish. With the 5 Towns, you have a place that people want to believe is the epitome of a successful up-and-coming community, the “New Lakewood,” as it’s been called on the CR before. It’s worth publicizing the reality. Also, nothing the OP said was personal; he didn’t single out individuals or institutions. The only people who would take personal offence with his grievance are those clinging to this strange, Utopian dillusion.
