Because without FPTP there would be no 'Labour' or 'Tory' party as we see them now. The only reason that Starmer/Corbyn and Stewart/Badenoch ended up in bed together is the idea they could get absolute power over the nation with less than one in five of the electorate voting for them. Proper representation would see the end of those behemoths of ferrets fighting in sacks in search of absolute power
Imagine you being able to vote for Starmer, your brother for Corbyn, Sensible tories for Stewart and Nige and Kemi fighting over the racists, morons and swivel eyed loons.
And I NEVER underestimate the stupidity of the British Electorate
These two parties have steered the UK over the last 100 years.
Won a war. NHS. Nationalization. Privatization. Joined the common market. Left the EU.
There is no reason whatsoever that ditching Fab and appointing the Barnet manager (via PR)
would transform The Albion into a multi league winning machine.
I rest my case.
