the KSCM in Czechia is very, very explicitly not ML. That would literally be illegal

Um yes that's why they say they are not lol

The French had a trot prime minister

What does this have to do with anything? They never had a trotskyist party in power or even represented. Greece had an ex trot prime minister, that doesn't say anything.

their most famous communist is Mélenchon (A trot)

...an ex trot who was only a trot like a million years ago who runs a multi tendency party, most of which isn't trotskyist.

was endorsed by the French communist party

...which isn't trotskyist

also both ran and got 2% of the vote as open trots.

...which completely pales in comparison to the records of the PCF in the past and in some cases present. Wow, 2 people ran as trots within a multitenency movement for national assembly and got a tiny share of votes. Um OK, so does the PCF, except that one also used to be the second or third most powerful party, and still is influential in local politics.
