In fact, I just saw a video recently from Russian YouTube showing a mosque that had been constructed in Moscow. So, even Muslims are allowed to worship in Russia.
***************
Yet all Christian denominations, other than Russian Orthodox, are prohibited from inviting anyone to church or sharing threir faith. The Russian Orthodox Church has returned to the same status, that it had prior to the 2017 revolution.
No, they are being prevented from promoting their churches. But, that is no better or worse than being harassed by homosexual activists and the government in blue states in the US. And, you're able to homeschool your kids without being harassed by the government as well. And, you're free to speak out on homosexuality and other moral ills without risking losing your job.
I'd say the level of freedom if you're not Russian Orthodox is about on the same level as a blue state here.
