I am sorry I don't understand that you wrote in Greek but I want to say something.
First to poet, Partizan was founded by the army, not by police (cops). But, Red Star was founded by cops. You are wrong my friend.
About your oppinion I respect that. We have brain to think, so you can think without influence of other people and make your own decisions.
I want to say about knfes. Grobari are against using knifes in fights. Just, in last few years we lost 5 friends stabed by knifes, mostly from Red Star fans. Red Star fans started to use knifes in Serbia, not Grobari. I can't say that all Grobari are not using the knifes, but official decision of Grobari is that we don't using knifes.
Red Star fans can't complain about injures in Salonica, because they already did same things, lot of times.
So my friend Poet, be brother with Serbs, with Partizan, Red Star and all the other Serbian fans, it is your oppinion and I don't want to change it. But this is football, this is football fanatism, it is different from politics, wars... I like Greece, but I can't like OSFP, PAO, AEK... I like PAOK. It is different. And I made lot of friends (from PAOK fans) during all this years, for some of them I can say that they mean to me more then brothers, probably they can say the same for me. This is deep thing. Ask yourself what you did for some thing and then say complains. Ask yourself about guys who spent their time, money, health... for this friendship.
After all, even I don't think that this friendship is so perfect, we can do much much better, but I am very happy because I made lot of PAOK friends and it is priceless.
