The Liberals actually do have a man as one of their Status of Women Committee members.  There's no reason why men shouldn't work on status of women issues, same as there's no reason "settlers" shouldn't work on a committee about aboriginal issues.

In fact, it's interesting that the Conservatives removed Senator Beyak from working on the Senate aboriginal committee when she expressed views that opposed the treaty rights of aboriginal people.  IMO, if Ms Harder's political position is that abortion should be re-criminalized contrary to the rights of women, then she should similarly be disqualified from work on women's issues.  

I don't care if Scheer nominates a man or someone who does not call himself a feminist to chair the committee, but I do expect committee members would at least support Charter rights for women, including the Charter right to abortion.
