Menachem Shmei, when other Yidden say “tzaddik” they mean what the Gemora and Medroshim imply — someone who does the right things, does not do aveiros be’meizid (and if, chas ve’sholom, he did derech mikre, he does full teshuvah right away). It is very different from the Tanya’s chiddush of how to define one.
