The PSL’s prohibition on “horizontal”, viz., free communication between party members clearly has nothing at all to do with Leninist democratic centralism and everything to do with **Trotskyist **distortions of the very concept. Imagine if Lenin himself was not allowed correspondence with members of his own party regarding matters of the party except if his local leadership had allowed it. In the present day, imagine a scenario in which one party member was suffering abuse from another and, rather than help that member to safety and immediately launch an investigation into the matter, the instance was dismissed and covered-up under the guise of “horizontal communications”; this second scenario doesn’t need to be imagined, as it has actually happened to myself and others within the party.

Marcyist, Trotskyist, what's the difference comrade, we have newspapers to sell. Please know that I won't bad-mouth a communist party publicly, here I am among fellow Marxists (and some Anarchists), so its different.
