Couple of things to deconstruct here: You describe yourself as a decently hard socialist and then claim there's no entryism. That's like saying that I'm a white bloke and racism doesn't exist because nobody ever called me a racial slur. Your argument that Labour was a socialist party 100 years ago holds no merit in terms of what the direction of the Party should be today because we don't live 100 years ago. You also fail to mention that that 20 year period was arguably the most successful Labour period in the Party's history. The Tories and Labour are not ideologically opposites of each other and agree on about 95% of issues in society and always do. It's the 5% we focus on.
