I agree with you that Russia has a very gruesome past in their suppression of Muslims. The reason more Muslims don't know about the worst excesses that Russia committed is because there's no single source of information on the subject, like a book. During Tsarist times there the Russia-Turkish wars and the Circassian genocide. But the worst repression happened during Communism, which was a horror that killed 20+ million Russians of all faiths. Most most mosques that were destroyed were during that time.
It so happens that most of the Bolshevik leadership were Jews.
Douglas Reed writes: “The Central Committee of the Bolshevik Party, which wielded the supreme power, contained 3 Russians (including Lenin) and 9 Jews. The next body in importance, the Central Committee of the Executive Commission (or secret police) comprised 42 Jews and 19 Russians, Letts, Georgians and others. The Council of People’s Commissars consisted of 17 Jews and five others. The Moscow Che-ka (secret police) was formed of 23 Jews and 13 others. Among the names of 556 high officials of the Bolshevik state officially published in 1918-1919 were 458 Jews and 108 others. Among the central committees of small, supposedly ‘Socialist’ or other non-Communist parties… were 55 Jews and 6 others.”
The simultaneous triumph of the Jews in Russia and Palestine was indeed an extraordinary “coincidence”: Divine Providence drew the attention of all those with eyes to see this sign of the times when, in one column of newsprint in the London Times for November 9, 1917, there appeared two articles, the one announcing the outbreak of revolution in Petrograd, and the other – the promise of a homeland for the Jews in Palestine (the Balfour declaration).
Indeed, the Russian revolution may be regarded as one branch of that general triumph of Jewish power which we observe in the twentieth century in both East and West, in both Russia and America and Israel. The mainly Jewish nature of the Bolshevik leadership – and of the world revolution in general – cannot be doubted. Such a view was not confined to “anti-Semites”.
