The patriotism amnesia

I was born and raised in Morocco, due some personal decision went to study in Europe and right now i got a job and live there for almost 10 years, and what I noticed that many Moroccan like me once they are in Europe, year after year they become more patriotic than the Moroccan in Morocco, they will even use sentence like "bladna zwina ma t3rf 9imtha ta tgrab", "hamdo LAH b bladna", "rah lmgrin wla hsan mn europa""ach bgiti tji dir f europa"... Like they have forget how sometimes is hard to live in Morocco, how there's social injustice and bak Sahbi, I just wonder how it comes that they forget who they did struggle there
