Protest

"For the first time in 20 years, the Islamic Republic of Iran has issued a formal death sentence for a Christian. Pastor Youcef Nadarkhani, leader of the Church of Iran denomination in Rasht, was arrested in October 2009 while seeking to register his church. He has been on death row since being found guilty of apostasy, conversion from Islam, in September 2010...Although apostasy does not carry a formal death penalty under Iran's penal code, judges in Rasht were able to use the supremacy of Islamic jurisprudence in Iran's constitution to sue for the death sentence based on religious fatwas, or Islamic rulings, by leading Ayatollahs.

Regardless of your opinions on religion, I don't think any right-minded person would agree the executing someone for their faith is acceptable.
