You can still be utterly opposed to 'blinkered Marxist ideology', even if I think you have little idea what that actually means amigo, bar anti Left sloganism. Here's a very wee leg up. Pretty basic stuff however. The Corbyn and his Marxist Labour Party Manifesto position is utterly ridiculous as Gareth has pointed out and shows that this particular trope, one of many including anti-Semitism, by the billionaire owned MSM, Tory and Right wing Labour MP's, Labour Party Blairite beaurocrats conspiring to prevent a Labour Government, obviously got through to many. However Keir Starmer's ridiculous campaign for a second Brexit Referendum cost Labour dearly in Northern Labour Brexit seats. Not mentioned now. Airbrushed.
These may bore your pants off amigo , there is no shortcut to understanding mate, however may give you a glimpse of what Marxism is about and not the stereotypes you have. Watch Tony and reject the ideas at will. At least you can reject out of hand objectively. Grab some beers.
