The odd comment doesn't mean much in the context of handling public perceptions, sure. I care more about actions than words-- but his actions thus far, expelling party members for faint left-wing sympathies, also contribute to the impression that he doesn't intend for his party to represent the (centre)-left.The odd comment in a right wing rag no-one under the age of 50 reads disappears like a pebble thrown into the ocean.
I agree in a sense that Labour needs to build a new narrative. But it does that by winning an election and governing. As long as there people who feel fondly for Thatcher still alive and voting in strength who are never going to change that view, a spot of rhetoric to keep them happier to win that election is neither here nor there. And eventually they'll die of old age and such lip service can end.
If Labour's still talking up Thatcher after it wins an election, then I'll be bothered.
And sure, if the election comes and he then switches tack and improves things, my complaints will melt away. But the last time Labour echoed the conservatives in order to win a convincing victory, they didn't shift back to humane government after taking power-- we got PFI and oil wars instead.
I mean, they'll get my vote because the only credible alternative is inarguably worse. But these are among the reasons I couldn't be a member. They make it clear they don't want me.
