There is a big difference to the 1997 labour party leadership than now, only idiots compare starmer to blair.
blair for his faults was a better leader and politician for one and also stuck to what he believed in unlike starmer who will change ideals for likes, also Blair employed different parts of the party to achieve his goals, that is why you had Brown, Straw, Prescott, Blunkett, Beckett etc, a mix that ranged from left, center and blue labour.
Starmer has a buerocratic almost stalinist need to purge anything that is evenly slightly off his message, and a need for complete control and obedience, something that is the antithesis of what labour has always stood for, unity, tollerance or ideas, collectiveness.
Also he will lie and change his views at a drop without an hinest word from his lips
Plus the overton window has shifted over the last 40 years rightwards, and what was blairs centerism now is left of starmers, which is more closely atuned to Cameron and Osborunea soft conservatism.
I have abandoned labour natioanlly now as it does not represent my values even those that are centre left, at least under Blair it still, at core was a soft left party with some neo-liberal lurches, now it is nothing I recognise as Labour
