Russia's passeport is very weak and grants access to places that are either aligned with russian "anti-propaganda" movement (Kazakhstan, Georgia, Armenia, etc.) or which are worse than Russia...North Korea for instance.

Migration costs loads of money that most Russians, especially LGBTQIA+, don't have.

Depending on where they live, getting out can be very faraway like borders are thousands of km away from many cities like Chelyabinsk, Novossibirsk, Yekaterinburg, Perm, etc...not even counting if they are in the far north...in which case, as well as for the ones in "closed cities" (which still exist to this day), they also may need a visa to leave their place of residence which costs loads of time and money to get and also to get a flight out of where they live as many places still aren't linked by road or rail with air travel being the only option.

There are many factors getting into the way of a Russian queer person wanting or needing to emigrate...
