People of your ilk have been thinking like that for 50 years. Unless Labour and their band of immature momentum followers take a dose of reality the majority of the electorate will continually suffer because of it. You lot keep putting in power the very people you despise.
The problem is people like you who have it in their heads that this election somehow about a test of socialism and that this proves its dead which is bullshit. The election was first and foremost about Brexit anyone who can't see that needs to give their head a wobble. Secondly it like all elections was about the people that we were electing and Johnson won hands down. Pretty much everything else pales in to insignificance. the tories had virtually no policies and Johnson avoided scrutiny at every opportunity and when he did he beat the same drum get Brexit done!!
Now I don't know what you and the rest of these anti socialist don't see maybe its your desperation to say socialism is dead we told you so. But it isn't and as long as there are decent honest human beings around it would always be around in some form or another. A strong leader who is liked by the public and a simple clear message and you won't be beating the same drum come post the next GE.
