I think that this question should be closed as, talking about russian radicals and racists, they aren't distinguishing people by the religion, and they barely know the difference between muslim and hindu (they main idea is Russia is for Russians
, they even can't say what exactly Russian
), so the referenced questions, in general, answer your question:
Moscow and Saint-Petersburg are two biggest cities in Russia, and staying in their center part is reasonably safe, if you do not enter some suspicious bars and do not talk to the suspicious people.
However, train to the Vladivostok and Skolkovo is different, as there you'll definitely attract the attention of locals, so, if you can, find a company to these trips. Robbery in trains isn't a rare thing, regardless your skin and religion, you just should avoid strangers. About the pork and alcohol, I don't think that it's a real danger. If you're in conflict, your health is in danger, not your soul.
Also, Ukraine and Russia are different countries, so you shouldn't use some cases from one country to make a decision about another (there are more aggressive radicals in the Ukraine than in Russia).
