Amen. I think this in part stems from a more general phenomenon I’ve observed which one might call the subtractive identity problem of dissident sects, where the identity of a movement and the people within it becomes based almost exclusively on how they differ from whichever group they originate from, rather than The whole of their beliefs.
Seventh day adventists, for example, share plenty with the mainstream groups that precede them, but their movement and identity is centered on how they differ—particularly seventh day sabbath observance (as well as things like the ‘investigative judgement’).
For believers affirming the fullness of Torah as binding on the contemporary believer, this often comes down to centering our identity on the commonly neglected commands (sabbath, dietary laws, etc.) and consequently neglecting some of what Christ called the ‘weightier matters’ of the Torah (justice, mercy, and faithfulness) and those that all the law hang upon(to love God with all our being, and our neighbor as ourselves).
I do use terms like ‘Torah community’ or ‘Torah-affirming Christian’ often, for lack of any better terms that I’ve thought of or come across, but I try to be careful not to operate in or imply a reductive worldview in using them.
I might write an article about this in the future now that your article has prompted the thought. (:
