Malaysians fire-bomb church over "whatever-you-call-him"

Three churches have been attacked in Malaysia's capital Kuala Lumpur, ahead of protests by Muslim groups.

The administrative offices of one church were destroyed by a firebomb attack and one of the other two churches attacked was slightly damaged.

Some Muslim groups are angry at a court decision allowing non-Muslims to use the word Allah to refer to God.

The government of the mainly Muslim nation has condemned the attacks on the churches and vowed to take action.

About 60% of Malaysians are Malay Muslims and the government relies on their vote.

There also significant Chinese and Indian minorities, who are mainly Christians, Hindus and Buddhists.

The controversy stems from a ban on a Catholic newspaper, The Herald, using the word Allah

If the Christians are already of another faith altogether, what should it matter how they chose to refer to their deity? Is there a concern that if Christians refer to their god (which is historically supposed to be the same god of the patriarch Abraham in both faiths) that the Muslim faithful will suppose there is no difference, and they might as well be Christians? Or it it a question of formality--as in: I only know my neighbor well enough to call him "Mr. Smith", but his real friends can call him "John"?

I'm sure these are questions that would befuddle a believer as well as a kafir. But the fire-bombings take the place of much exegesis, don't they?
