Simcha613: You are absolutely wrong. Chas V’Shalom to call someone a slob because he follows the Torah, whereas your illogic leads to the conclusion that only by violating the Torah can one avoid being a slob.
This above point is absolute besides my previous point that between shaving and not shaving — all year round — if one is to be considered slobbish, it is the act of shaving – while not shaving is mentchlich.
And, no, an aveil is NOT a slob by not shaving. He would be a slob if he shaved.
