Well, the pregnancy avenue is a significant area of unfairness between the sexes. Women of childbearing age DO have that hanging over their head precisely due to federal law.
There's 2 ways to fix it. Get rid of the federal law (and deny that pregnancy carries complications!) or offer the same benefit to the male.
I'm for offering the same benefit to the male. And now, that both have that law, the differentiation becomes moot.
I have become more open to the idea that the US is a wildly different place.
However it doesn't matter. For the individual person arguing a different point of view you can only succeed in persuading them if you respond to what they are saying fairly and charitably rather than argue with straw men and shadows from your own mind and fears.
That is what I am saying. Your ontology of the argument is too austere. People have other beliefs than women should be able to work or not.
