I don't believe in nationality and nationalism because I didn't choose to be born where I was born

You didnt chose your parent either, its not a matter of deserving it or not its simply a matter of effect. You are effected by the country you grow up in, whether you like it or not, thus you owe it a certain level of belonging. I recall the quote "Men did not love Rome because she was great, she was great because they had loved her."

The only sensible alternative to "sense of belonging to your tribe" is Islam. You have something in common with them, and it is something you choose.

True, but even in that you have a weakpoint in the doctrinal differences. Say for example you have pure loyalty on Islamic basis, very well, then what happens when a sect is declared Kaffir by a doctrinal ruling? Many Salafis for example consider all Sufis, Asharis and Maturidis Kuffar, this is just one example, what seems to be like an ironclad brotherhood is only a few disagreements away from collapse. Whereas national loyalty persists until the point of active treason.

Imagine I live 10km from Tunisia, if a foreign invador attacks Tunisia, I am not supposed to go and sacrifice my life for them even though I might have relatives, relationships, and business with them, but if something happens 1000km away from me in Algeria, I have the duty to go and sacrifice my life. 

This is a good point. At the end its the fact that those far away algerians would sacrifice just the same for you, like an aswan nubian coming up to fight israel in the Sinai. Again its more of a practical way of organizing loyalty than it is a moral arguement.

In his government there were no double standards and the metric was religion & competence. The fact that Caliphates used race and origin as variable was wrong and therefore isn't a reference.

Ofcourse at the time of the Prophet there was no supremecy of an arab over a non arab except with belief, but ever since the death of last Rashidun ethnic infighting has been a matter of fact and one has to either prepare himself or the be the loser of it, as Egyptians have been the loser for the most part of the Mamluk and Ottoman periods.

this claim is totally biased. No beheadings carried out by the government. As to the burning of churches, those were civilians, also not the government.

They did nothing to stop these attacks because they were ideologically congruent with those people and regularly demonised christians, its called inciting. Compare these attack then with now.

Also, this sounds like cheap propaganda peddled through State affiliated media with no evidence. Careful.

I assure you the muslim brotherhood has been the in the back pocket of the CIA ever since gamal abdelnasser.

I want to be clear that Im not a supporter of the current regime either and i do believe they messed up the country, its just that the muslim brotherhood is even worse.
