alexpolismum - You need to read the Quran and some hadith to have an understanding of how and why Muslims think/act re these topics.
"I think your point about freedom to worship is debatable and not clear cut. if a Muslim converts to Christianity, should he not then be considered a Christian and be given freedom to worship as such?"
It's actually rather "clear cut", as the majority of Muslims, especially those living in fundamentally religious countries like Iran, believe Quran is the literal word of God, sent down page by printed page to illiterate Mohammad. And in the Quran, it says apostates are to be slayed wherever they are caught. Iirc, hadith are a bit gentler, and say first you are to talk to him and try to make him come back to Islam. If that doesn't work, separate his wife and children from him so he doesn't "contaminate" them. If that doesn't work, killing him is "what should be done". Don't quote me on this though as I don't remember the particular hadith. Perhaps one of the Muslims on this thread can help.
"With regards to Turkey, I do wonder sometimes if this will change now that Erdogan's party is takeing more and more control and uprooting the military establishment"
Erdogan has been in power for many years now, and Turkish army has not lost its power, regardless of what you might read in UK newspapers.
"Also, I notice that Turkey's tolerance does not extend to the Halki theological seminary."
Penetrating powers of observation. So you "notice" that a minor school on some island was closed 40 years ago and that means... what, exactly to Turkey in the year 2009?
This is the problem with Googling on an insufficient knowledge base - you actually think you know a country because you read "Halki theological seminary was closed by Turkish state" or some such Did that website not mention that ALL private universities were closed in 1971, not just Halki?
And do you "notice" that Greek Orthodox Church still operates out of Turkey? What does that mean re religious tolerance in Turkey, do you think?
If you visited Turkey, do you think you would "notice" synagogues and churches open for worship? What do you think that would mean re religious tolerance in Turkey?
Apologies to the thread for going off on this tangent, but it pisses me off when people read a few sentences from a Google search and are instant experts on any subject.
