Now, now. Starmer might not be a militant marxist, but he spent a good chunk of his life fighting for workers' rights in court. He also served faithfully in the shadow cabinet under Corbyn - are you saying that Corbyn chose a "corporate stooge" as his shadow minister, and on the hottest issue of the day at that (brexit)?
One of Corbyn's lackings was that he was unable to make friends in his own party, to the point that half of his own rank & file literally sabotaged him at the last election. By calling good people all sorts of unwarranted names we're only going to see a repeat, and $deity knows this country deserves better than yet another Tory government.
