You can fight those who threaten you or those who you think threaten you. If you are a mobster in a lawless environment, you can fight using mob methods, just as Lenin fought against the tsarists, the bourgeoisie, and other perceived enemies of the proletarian revolution.
You can fight the powerful, even if they are not hostile. What if they decide to use their power against you?
You can fight your competitors. Comrade Stalin, for example, killed every single one of them. What was I to do, he would have said in his defence. Had I not killed them, they would have killed me.
But what is the point of fighting transgender people? They do not threaten anyone, are few in number, and have so many problems that most of them could not care less about the bigwigs’ political games. The same goes for the rest of the LGBT crowd: they are mostly non-political people who have it tough all over the world, and especially under such a regime as Russia’s.
So, Russian authorities launch an anti-LGBT campaign in the midst of war. But that is not enough for them: step by step, they are taking action against gender reassignment. And they have almost succeeded. The Russian parliament has passed in first reading a law that forbids LGBT people to change their physiological and social status to match their identity.
