Excellence: Very true. It’s like that old (sad) joke of Moshiach going into a Chassidish Steibel wearing a fedora and was rejected because “how can Moshiach not be wearing a Streimel, then goes to a Yeshivish Shul wearing a Kippah Seruga and the same thing happens….all the way down the line until he gives up and leaves.
People judge too much on externals. B”H, it’s not always that way. Before making Aliyah, I Davened in a Chassidish Shteibel for a very long time. The Rov, ZT”L was a real Tzaddik, he was a Satmar Chosid, yet the Baal Koreh wore a Kippah Seruga and was a YU grad. It didn’t matter to him. He looked at everyone individually for who they were on the inside.
