They want to see Buckingham Palace become a mosque

I agree. For example, the Palestinians

What religions are Palestinians?

If the Palestinians weren't so stifled by the irrational tenets of Islam they would have whooped Israel's butt ten times over already.

How many groups in the PLO are not religious ?
How many are religious but not islamic?
The tenets of Islam have bugger all to do with their failure, the failure is due to all the groups and all the other nations supposedly backing them following thier own different agendas based on their own national and political interests
