I don’t think that Iranians get along with each other, in general.
They don’t hold the patience, ethics, and intelligence that is necessary to hold different people of a nation together. They don’t understand, or respect each other’s differences, and try to suppress every single difference they see in others. The hold on to any possible power, way, force, to diminish different people. They constantly make fun of every single ethnicity in their own country. What makes you think they should remain as one country? Iranians are the most ununited, disrespectful, ignorant, racist, and fascist nation I have seen my whole life. They don’t tolerate the tiniest difference. They will go for any joke, in any extent, to make it clear that they plan on making fun of other people. They have small balls, and are usually intimidated people, but they will find any chance to belittle others, to label them, to publicly shame them, to make a point about their culture, their existence, their being. Honestly. I hope the country will be torn down. If anything, Iranians have proved they are not ready to establish a country that size. Different races must leave, and take their lands with them. I would say Persians and Azeri people (people in Azerbaijan-E-Sharghi, Yazd, Isfahan, Tehran, Albortz, Ardabil, Kerman, Semnan, all Khorasans together, Mazandaran, Fars, these can live together. They have mouths big enough to burn each other.
Iranians are so selfish, self-centered, and racist, that they would go to any extent to put people down, with direct offenses, or as “jokes”. It doesn’t matter if they are your friends, or they date you. Majority of them are sadistic people, obsessed with something, and angry at everything (mostly, the provinces I mentioned above, not all Iranians. I am talking about cities, in general, not the small towns and villages. They are very good people, in general). They will come out of the blue and will start offending you, no matter how polite, silent, and considerate you are. They will continue doing whatever their parents have grown inside them, to finally bring you down, make you one of them. OR that you leave them, which doesn’t happen usually. Because such a person is abusive enough to never let you run away.
I hope that the country will fall apart, for everyone’s good.
