What nonsense! What kind of mixing could there be, for example, with Muslims? They don't want to mix. They are influenced by a backward religion. Just like the Jews, who still consider themselves chosen by God.
Socialism also means the real separation of religion from the state apparatus.
The madness that exists today in Western countries with their policy of “tolerance” is impossible under real socialism.
You don't want a Holocaust? Fight for socialism with its policy of internationalism.
And internationalism does not mean that people must obey ancient, ugly, and backward rules and traditions. Religion, any religion, is part of what humanity must throw aside in its development, if only because every religion considers itself to be the only true one and therefore irreconcilable with others. We will not unite humanity this way.
