Are you saying you have the same principles as the Muslim fundamentalists in Iran? You agree with what they do?

From the internet:

In stoning to death, the victims's hands are tied behind their backs and their bodies are put in a cloth sack. Then, this human "package" is buried in a hole, with only the victims heads showing above the ground. If its a woman, she is buried upto her shoulders. This is to give her an seemingly equal (but nonetheless impossible) chance to escape recognizing her lesser physical strength.

After the hapless individual has been secured in the hole, people start chanting "Allah hu Akbar" (meaning, God is great), and throw palm sized stones at the head of the victim from a certain distance (a circle is drawn).

The stones are thrown until the person dies or until he/she escapes out of the hole and crosses the circle. Escaping is impossible, given that the individual's hands are tied behind their backs and they are buried in a hole upto their necks or shoulders (in the case of males and females respectively). Naturally, the procedure is extremely barbaric and bloody.

Most often, women are stoned to death, usually for prostitution. If they are mothers, their children are often required by law to attend the atrocity, to watch them "repent" for their sins.

On . . . June 29, 2006, a court in the Islamic Republic of Iran sentenced Malak Ghorbany, a 34-year-old mother of two, to a brutal death by stoning after finding her guilty of adultery. . . . Two men who were found guilty of murder in the same court were only given jail sentences of six years. . . . The size of the stones used during the execution are required to be . . . not so large that they would kill a woman too quickly, nor so small that they would fail to cause serious injury or pain .
