Agreed. The article is premised on mothers being primary caregivers. The syllogism for the opposition on the proposed change on taxation is unclear (even if the proposed change are ill-advised). But beside the point, the stereotype that mothers are the primary caregivers is not accurate. I know of many two income families where the fathers are far more involved than the mothers in taking care of the children and the ageing grandparents, as well as traditionally female roles of housekeeping, cooking, grocery shopping, and laundry, (and they still mow the lawn,  shovel the snow,  fix the deck too!).
