Well since you already have your prejudices and will not be persuaded by any point that is directed at you this thread that you have started feels a bit pointless.
Labour's taxation policies reflect their belief in distribution of wealth as a means to create a more egalitarian society, fair enough this undermines the incentive to work hard in our current meritocratic society, but it is fundamental to understand the importance of this upcoming election for the safety of our NHS and various other public services. Let us be clear, it isn't going to be the Liberal Democrats, The Greens or the The SNP who form a government but under FPTP it is bound to result in either a Conservative government or a Labour government. The Conservatives under Thatcherite leaders like Johnson will continue with their agenda of austerity and further their neoliberal ambitions, the alternative is where we have to choose the party that emphasises on the more human element of politics, you have every right to dispute that claim but in its essence, there are only 2 clear options on the table; to maintain the status quo and thus accept the brutal implementation of austerity measures and give the government a mandate to continue with them, or to reform our political system so that it works for the many and not just the few.
I myself am a Blairite and therefore am quite distant to Corbynite politics, but when our NHS, Education System and other essential services are on the line, when our frontline workers such as the Junior Doctors, nurses, firefighters are let down continuously, I feel it being a moral duty to suck it up and side with Corbyn's Labour as a way to defeat this current government.
