I consider that remark a slappable offense.
I encountered precisely that attitude, about 15 years ago, during an inadvertent visti to an "independant" Traditional Latin Mass chapel in Chesapeake Virginia.
I didn't go back.
The chapel has since gone legit, and changed its name.
Well you sure showed them! Looking back with the hindsight of 15 years, don't you have to wonder if you did the right thing? Especially if you live in the Diocese of Richmond where the priests who are given parishes are the ones who drive their motorcycles down the aisle.
I have attended Mass at that chapel, and I have to admit that the people did come across as somewhat cold and standoffish. But that wouldn't stop me from attending the traditional Catholic Mass.
