The Tolkien society is hosting a woke seminar about Lord of the Rings this summer.
Just a few of the talks are titled “Gondor in Transition: A Brief Introduction to Transgender Realities in The Lord of the Rings” and “Pardoning Saruman?: The Queer in Tolkien’s The Lord of the Rings”.

There was mentioned: German society about 1000 members.
THE Tolkien society (English, which you mentioned above) supposedly having 3000 members.
Miniscule club! Not relevant for the fandom.
(And to my knowledge definitely a different entity to the body which is advising the coming LOTR amazon series).
