A short by a disenchanted green activist gives an insight into the mentality of a number of Corbyn supporters, it seems to me.
He complains that his former party has recently prioritised elections rather than "community politics" by which they seem to mean issue based campaigns that raise awareness.
The Labour Party in contrast has as the aim of the first clause of its constitution the need to get a parliamentary majority. This attitude also extends to other bodies such as Councils.
It is not incompatible with real community change. Indeed, it is the only way to do it on a big scale. Even on a small scale it can make real changes. The Green Party approach described is more about protest as a performance art without responsibility and without significant change.
It is an odd view for anyone who believes in a pressing climate emergency to take.
