One thing about Margaret Cho: She isn’t the quiet type.  The multi-hyphenate performer—comedian, actress and singer—has always been outspoken about politics (she’s an avowed liberal), sexuality (she’s bi) and social issues.  So it was amusing, in a way, that the voluble Cho, 40, has been silenced the past few weeks since developing nodes on her vocal cords.
