That's not saying anything. As an "equal"? Well, they get the same prices as everyone for trade, I guess. So do the US, Japan, Russia, etc. But none of those have a saying in european politics, including Turkey.
Yep. Only a bit earlier they had been part of the Persian empire and later in their history came the Ottoman empire. Both of them had as a goal to overrun Europe (the former the Helenic civilization and the latter Europe itself). Thankfully they both failed. Please note I'm not holding some kind of historical grudge here, it's just they are historically not a part of Europe, and they have a rather distinct culture. And as someone said before, we should fix the house first before inviting more guests in.
