ujm,
“Being Chareidi has close to zero to do with externals such as dress, speech or mannerism. It’s all to do with how to implement practice of halacha and hashkafa.”
Yet there are certain externals such as dress and mannerisms that are defined as “chareidi.” Just as there are externals such as dress and mannerisms that are defined as MO/religious Zionist, like when I get an emphasized “ShabBAT ShaLOM” back in response to my “gut Shabbos” to someone wearing a srugi. People want to identify as part of a group, and that’s ok.
