The older I get, the more I believe that 'equality' is nothing more than a smokescreen to prevent the true liberation of women. Equality before the law means nothing when violence is endemic; when women are most likely to live in poverty; when no one bothers to actually enforce the existing equality legislation.
Mother's Day, in its present form, is merely a another capitalist-patriarchal tool to beat women over the head with. It remains nothing more than a depressing attempt at brain-washing women into believing that 'their' work is valued. Women's work has never been valued. We still do the majority of the childcare and housework whilst in paid employment.
