While I agree in principle I don’t think that would necessarily change the results in this case as labour was the best mainstream option in that case. The conservatives had messed up badly and lost public confidence, bleeding votes to both Labour and Reform.
You think that Labour are hard left? They literally kicked out all the actual communists and other far left people years ago. I don’t think you have ever seen what real far-left organizations look like or believe - I actually used to be a member of one some time ago if you wanted to ask. You’re either misinformed or a lot further right than you claim. It doesn’t surprise me people are applying that label to you given what you have just come out with.
