The government of Russia ≠ the people of Russia. Men are just a gender. There is no government of men. When you say "men are the problem", you are talking about individual men and men as a whole.
Obviously you are technically correct, but I still think many feminists use "men" as a shorthand for the broader male-dominated system. If I say "I love the way women smell" I really don't need to clarify that I probably don't mean all women in all situations, it's kinda obvious.
Where is the outrage over any of the injustices that men face
That's a logical fallacy. There probably should be more outrage about those things, but that doesn't change the initial situation.
