Those examples don't contradict the claim you're denying. The claim wasn't "men had it worse than women". It was that capitalism originally hurt men (coal miners, specifically). The commenter was arguing that capitalism is not a plot by the patriarchy devised to oppress women. To contradict their claim, you need an example of capitalism originally victimizing women.

I doubt anyone here would disagree that women have suffered more from sexism.

Incidentally, and unrelated to that point, you chose oddly mild examples of bad treatment of women. I'd much rather live in a society where I couldn't vote or charge my spouse with rape than be a coal miner and suffer from black lung and be in significant danger of dying in a workplace accident. You could have gone with the awful treatment of women under the Taliban, to name one example.
