It’s not unreasonable for people to prefer a certain type of atmosphere when they go to a restaurant (or anywhere else, for that matter).
This is not close-mindedness, but simply a matter of personal preference.
I resent the allegation that my choice to avoid restaurants with a certain atmosphere means that I am a judgmental person
I see no problem with a hashgacha catering to its clientele, even if only as a business decision.
You seem to think that the hashgacha both (a) has no place regulating anything other than actual food kashrus, AND (b) should tell people not to judge.
