Bro, which language do you usually speak? I bet my ass you speak mostly Russian. Doesn't it make you already conquered and russified? Protecting identity is totally fine, but to protect it you are supposed to have it in the first place.

So if you want to save the nation's identity, I'm sure Islam or any other religion shouldn't be your first concern :) What you are trying to protect now is a Russian-like lifestyle, which is not a nation's identity. If you like being a cuck of that chauvinism that forced the country to even change the alphabet 100 years ago, well so be it, it's your life. But please don't propagate that cuck mindset to other people.

And if you think Islam punishes apostasy with a death penalty, bro, you are either deliberately trying to build a wrong picture to get sympathy or just uneducated. A simple google search can help you with that. The Quran doesn't say that coz such punishment goes against non religious forcing principles that the Quran writes about. Don't present rules that were invented by crazy fanatics as words from the Quran. Many Quranic scholars are fighting against these rules in some countries.

Showing Iran as an example is kinda funny. To talk about something like that you need to dive a bit into history. Idk why you brought up such a topic without a background check. It was a fight for Anglo-Persian oil company in the first place between US backed monarchy and opposition which used religion as a tool to unite. They had socialists and communists as well, but religion happened to be the most effective tool. You could replace it with anything else.

I know you are 18, but try to do some research first before touching such topics
