Yes, Alceste's grasp of logic is certainly challenged.  If all women in Canada were pro-choice, then perhaps her argument would hold water.  But a sizeable minority of women in Canada are not pro-choice.  Should their views not be be represented on the Status of Women Committee.  The chair has no special powers, and the plurality of pro-choice votes on the committee is more than assured.  So what is the issue?  The Liberals saw this as a chance to score points by making something out of nothing.  And now it is blowing up in their face.  Serves them right.
