It is understandable that some are afraid of Muslims because of the 911 attack and the many bombings around the world (especially in Israel).
That fear motivates political decisions to limit Muslim extremists (those who join Jihads, one definition of which, according to the Encyclopedia Britannica, is a fight against the enemies of Islam). Wikipedia goes further and says that a Jihad is a war against non-Muslims.
Indeed, Solmon Rushdie's book "Satanic Verses," which cast the beleaguered Islamic religion in an even worse light, resulted in a fatwa to assassinate him.
Christians should find it in their hearts to forgive those who fear and try to limit the power of a group of people who have been proven to make attacks.
To be politically correct, one must not blame the actions of all for the actions of a few (such actions would be construed as bigotry, despite the large numbers of incidents of terrorism).
Some cite the Muslim religion, itself, with issuing orders to fight enemies of Islam, and claim that it is a part of their bibles (or holy teachings).
Islam and violence - Wikipedia
Sharia Law has remedies such as beheading, flogging, and stoning. It seems rather mild for a teen to be merely arrested and questioned for possibly being involved in a jihad. Surely asking questions is not a serious breach of politically correct etiquette?
In many people's opinion, freedom of religion is fine as long as it doesn't result in the murder or maiming of those outside of the religion.
Would it be blasphemy to try to worship something other than the Muslim religion if one lived in a Muslim country, and would it be fair for them to have a beheading if someone was accused of blasphemy? Wikipedia (link above) says "The hadiths, which are another source of Sharia, suggest various
punishments for blasphemy, which may include death."
Violence in the Quran - Wikipedia
The link above discusses violence in the Quran. Of course even the Christian bible has various incidents of violence, as well.
