Yeah, he sounds like a twerp, but I don't think you can really analye legislation that way. You can be warned of underlying goals and look for them, or think about where this person might be going with an idea.
But the legislation itself will not necessarily instantiate the individual's views, even an amendment they propose, and it has to be viewed on its own merit. The system is set up so that bills and amendments typically have to be somewhat moderate in order to pass. Good legislation often comes as a result of several groups proposing ideas and building on them.
Looking at rates of prosecution and comparing would not necessarily be a bad thing for women, it could reveal where women were getting the short end of the stick. I'm not a fan of requiring parity on things in general, be they employment figures or prosecution rates, I think its a mistake because it assumes that in a fair and just situation they would be equal and that is not always the case. But an awareness of disparities of all kinds is not a bad thing - I'd be more inclined to say that information needs to be collected to allow comparisons on a bunch of metrics.
