I personally don’t think they’re wrong and the kabbalah while well-meant ignores the real issue of Sinas Chinam. These terms accurately describe different segments of Jews whose approach to Avodas Hashem is internally and visibly different. Such distinctions have been made in Tanach, Chazal and throughout our history. Sinas Chinam is to do with hatred not descriptions.
And anyway, if it’s wrong to use these words then never use them.
