Being a Yekke, unlike most other sects of Judaism, entails being born a Yekke. Other sects include transforming, changing ????? and deciding to do what you want. Not Yekkes.
Actually, that is true with all sectors of Judaism. Nothing unique to Yekkes.
Not Chassidim – I’m afraid if that would be true, Chassidus wouldn’t exist – isn’t it a modern invention – like within the last 300 years?
