The Tory Party haven't definitely promised not to round up all the poor and have them shot. That'll probably be in the 2022 manifesto. "We definitely won't put in place extermination of the poor for the next few years, though we will look at ways in which we can eliminate a few of them for now"
Look I get it, you don't trust the Conservatives and their policies are not ones you agree with but ridiculous hyperbole like this doesn't really help you make your case IMO - or if you genuinely buy into the fact that the Conservatives are evil monsters out to destroy the country then the next few years will be excruciating for you
