The death penalty (as a maximal penalty, depending on the case) for homosexuality exists in the following countries:

Iran, Saudi Arabia, Yemen, United Arab Emirates, Sudan, Nigeria, Mauritania

I do not see a pronounced Christian influence in these countries.

If some extreme Christians want to follow that example that reminds me of the position towards evolution: The most extreme rejection is shared by Christian and Muslim fundamentalists (literalists).
