-passport stamps from Arab countries -
What's wrong with visiting an arab country? or do you believe in enclosing a race to their own land and prevent them from outside contact? Similar logic to that of a certain country, I must say.
Erm, have you ever tried to enter certain Arab coutries with an Israeli stamp in your passport? I don't think so. Israel will still let you in the country, just they make ask more questions and check you and your belongings out a little more. Some countries just wont let you in if you have an Israeli stamp, this is why some people have 2 passports, both from the same country.
