Really? Why particular one of the 76 indexes used is this going to negatively impact?
For reference, Canada scored a perfect 10 for gender, and I'm not thinking this will harm that.
I'm not sure which one it would be, although some freedom indices focus on property rights and the rights of business owners as their priority - oftentimes taking precedence over human rights. Capitalists often view their property rights as sacrosanct and think of their businesses as their own personal plantations. If the government taxes them or tells them they're not allowed to discriminate, they see that as a violation of their property rights and an imposition on their freedom.
