Why you should learn Arabic?
-You can speak in the native language of good people from the Middle East (see jveritas)
-If you are a Christian, how will you spread the Word of God to muslims (Arab or not) if they can’t understand you?
-Because it is heavily influenced by Aramaic (one of the languages of the Bible). I could understand quite a bit in Passion of the Christ without subtitles.
-So you can read the Koran in the native language and see exactly what we are facing.
-New markets for business.
-So you don’t have to depend on the lazy liberal media to tell you what Arab publications are saying about the West, Jews, etc.
-So you don’t look like an idiot (and get sued) simply because some guys are speaking their native language (people who are risking their families in Iraq if they are discovered).
And just how many languages do you propose everyone learn based on that logic?
And why just Arabic?
English is spoken worldwide. French is the international language.
