If you’re referring to the Bible verse Leviticus 20:13, well, I’m sorry to say that the excerpt from “The God Delusion” or wherever you learned this simplistic piece of misinformation is, in fact, incorrect. Shocker.
In fact, there is no account of capital punishment, in regards to this law (killing homosexual men), in Jewish history.
As for Judaism, Rabbinic tradition understands the Torah's system of capital punishment to not be in effect for the past approximately 2,000 years, in the absence of a Sanhedrin and Temple.
And as for Christianity, Leviticus and indeed the entirety of the Law of Moses was fulfilled by Jesus Christ.
And so no, neither Jews nor Christians practice this at all.
