Correct, Iranian does understand it is their regime to be blame, not Islam.
Wrong. Iranians strongly support their government (there's no "regime" in Iran, this term is used by mainstream media to demonize the Islamic Republic). Those who don't, are a minority brainwashed by the zionist and NATO enemy. Hence why they've consistently failed at threatening the stability of the Islamic Republic, despite the massive support they enjoy from the world's superpower and its entire array of clients.
Members of this minority camp of oppositionists, in their overwhelming majority are secularists at the minimum, and downright Islamophobic in more extreme cases. The entire political tradition of secular Iranian nationalism tends towards Islamophobia and/or irreligiosity, so does the liberal and globalist lot.
I showed concrete proof in the other thread (like that oppositionist person who did not want the Quran to be recited at the funeral of her son, like those mosques and seminaries torched by pro-western / pro-zionist rioters, like the campaign to knock off the turbans of clerics). Now if you need more it won't be a problem, I will post additional examples. But please don't turn the facts upside down.
Rather, inform yourself about authors such as Ali Dashti or Ahmad Kasravi. Individuals like these published books which would make Salman Rushdie's look like a harmless dime novel. Heck, spending more time at the Iranian section and paying close attention would be enough to get a sense of how secular Iranian nationalists think and the fundamental issues many of them have with Islam, and with religion in general.
We do have an Islamo-critical and even an Islamophobic political tradition in modern day Iran, which is quite similar to far-right Indian Hindutva ideology (only that in the Iranian case, Moslems are not a minority and the pre-Islamic religion, Zoroastrianism, is no longer a live religion effectively practiced by those referencing it, but merely a symbolic identitarian marker). It also shares a lot in common with the radical anti-clericalism and secularism of the Republic of Turkey under its founder Atatürk. It's the political heirs of this current, along with westernized liberals who today are rioting against the Islamic Republic - like it or not.
In short, don't be mistaken: if you're sympathizing with anti-IR oppositionists who rioted in the streets, know that you'll be endorsing a group which very much loathes Islamic governance. Choice is yours as to which of these options you'd prefer: you will either have the Islamic Republic in Iran or a non-Islamic political system (along with territorial balkanization). End of story. There's no other option in the reality of things, no matter what some outsiders might imagine due to insufficient knowledge of the subject matter.
By the way, practically every "Tweet" posted by the USA regime supporter in the opening posts, is showing scenes from Kurdistan province, where a minority of locals happens to be sympathizing with separatist terrorists backed by Tel Aviv, Washington and the EU. Obviously these kind of people would be cheering for their imperialist patrons. Even then, they do not represent the majority of Kurdish Iranian citizens, and the tiny gatherings they managed to pull off were literally dwarfed by the huge masses of Iranians who vividly celebrated the football win over Wales.
In short, another failed, deceitful propaganda operation by the zio-American empire, which may only fool the uninformed, the gullible or the hate-filled enemy.
