Soviet agents infiltrated the British gay scene many decades ago.
This was especiially fruitful for them back in the days when homosexuality was illegal and gay men could be blackmailed with ease and were much more easily honey trapped.

My understanding is that the Russian state works by infiltrating / bankrolling / astroturfing various activist groups and cults.
Their strategy is to infiltrate both extremes of opposing movements and then light the blue touch paper and stand well back and enjoy watching the fireworks as different "tribes" tear each other to pieces.
One thing that it apparent to me is that some elements of the Russian media are portraying the UK as a nation of child abusers who care more about pets and animals than they do about children.
An example is this fascinating interview with Camila Batmanghelidjh on the Voice of Russia radio station which contains some unusual claims
The current situation with Mermaids plays completely into this narrative of the Uk as a nation of child abusers as do the various conspiracy theories about VIP satanic paedophile rings.
It is worth noticing that when Carl Beech, the paedopile who falsely accused various innocent politicians, the head of MI5 and 6 and an elderly war hero of raping, torturing and murdering children, went on the run prior to being arrested he was in a remote and wild part of Sweden apparently heading towards Russia.
I don't have much time right now but there is so much more to add to this.
Readers may wish to research the astroturfing of the BLM movement in 2018 and 19 by Russian trolls.
Readers should also be aware that it is not just Russia, other actors are involved, Russia is however highly skilled at this kind of social engineering.
