About Shroud of Turin

Shroud of Turin is a linen cloth 14 feet 3 inches long by 3 feet 7 inches wide, bearing the highly distinct Image of a Crucified Man. Since the sixteenth century, the Shroud, believed by many to be the burial cloth of Christ, has been kept in St. John the Baptist Cathedral in Turin, Italy. From August until October 2000, the Shroud was displayed publicly -- for the last time -- in Turin, Italy. The previous public exhibition was in 1998 and, prior to that, 1978 and even before that, 1933, 1931, and 1898. And next exhibiton will be held in the Spring of 2010.

Question:

One of my Christian friends raised the issue of why Islam dictates that converters from Islam to Christianity be killed while Christians can freely convert to Islam. Can you please comment on this so as to convince people about the Islamic point of view?
Also, can you please comment about minority rights in Islamic communities such as practicing their religion and building churches?
Finally, can you please comment about Christian rights to make outreach for Christianity as Muslim do outreach (da`wah)
for Islam? In other words, do they have the right to make an effort to spread Christianity among Muslims as Muslims are instructed to spread Islam among Christians? Thanks a lot.
