I'd frankly be more worried about Albania or (shudder) Kosovo joining the EU than Turkey. If that ever happened then prepared to be very very afraid.

Turks btw are indeed known for being a bit short tempered, perhaps it's a cultural thing, they are also on the flip side a friendly bunch if you get to know them. They aren't alone, think the stereotype of the Italians - gregarious and prone to over the top emotional outbursts.
I've been to Turkey a few times, and in all fairness it's no dirtier than Greece (If that's a good thing). Beautiful coastline (The part I used to visit) and not particularly over the top with the religion side. This though changes as you get further inland. I wouldn't visit again - just got sick of various matters, aggression in shops a big one.

Then again, in a market in a pit of a resort called Marmaris, some local tried fishing notes out my wallet when I was paying something. They thought I'd back down - they thought wrong. They thought sending for their friend built like a brick ****house would intimidate me - I faced him right down. Don't mess with a Yorkshiremans wallet!!

Yes that's also a big reason I won't go back there - but in all fairness that could have happened in many other places popular with tourists, especially Paris and Barcelona.

Other big reason for not going there - Turkey, especially Marmaris is becoming the destination of choice for Chantelle to chav it up with the cast of "Shameless". The local men aren't impressed, and......it's not safe I reckon.

ps, Turk mentality - if anything "bad" happened in the resort, they used to say "Oh they won't be Turks, we are good people, those people owning that hotel/restaurant/scamming/.......they are Kurds".
Go figure on that one.

pps don't go to Turkey if your wife/daughter/granny has blonde hair.
