There are already some countries with different kinds of quotas for parliaments. Interestingly, reserved seats in parliament for women exist mostly in dictatorships (Saudi Arabia, China, Egypt, Pakistan), where parliaments have nothing to say anyway.
I wonder if the introduction in India now indicates that in India the parliament also has nothing to say anymore and is drifting towards dictatorship?
This is a bad idea that restricts voters' choices. If people want more female MPs, they can vote for them.
Plus the slippery slope of what other identity groups should get seats reserved for them. It's also not democratic so I don't really see how it could work in a western country, but then I've been surprised a lot recently.
