Peace be unto you,

There are many ways to respond to this. First, the Christian Church *did* execute homosexuals historically. In the year 390 A.D., Christian Rome formally prescribed the penalty of death for homosexuality. Second, there are still Christian groups today--such as the Christian Reconstructionists, the Christian Identity movement, etc--that still believe that this should be the proper punishment.
I would, however, agree with you that most Christians do not feel this way. Yet, the fact is that even if we say that the Old Testament Laws were abolished--despite Jesus [as] saying:
Matthew 5:17-20
"Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. Anyone who breaks one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven."
But even if we say that the Old Testament laws were abolished by the sacrifice of Jesus [as]--in opposition to his own words above--what we can say is that at one point in time God *did* himself advocate the death penalty for homosexuals, and the Children of Israel *did* use this punishment against homosexuals, and what they did was in accordance to what God commanded. Therefore, for a Christian to criticize executing homosexuals as evil is to call God's Laws evil, and to call God evil. For hundreds of years before Christ appeared, men were following the Law, as prescribed by God Himself. And according to Christianity, Jesus is God--they are one and the same. Therefore, according to Christianity, for hundreds and hundreds of years, Jesus [as] called for the killing of homosexuals.
Nonetheless, perhaps I should have reworded what I said, and merely said that the religious
books of all three religions--of Judaism, Christianity, and Islam--call for the execution of those who commit homosexual acts. As for the Islamic view towards homosexuality, I have clarified in the post I linked to. The Islamic punishments (
hadood) are specific to Muslims, not to Non-Muslims, who are allowed to live under their own laws as they please.
