Firstly I do not mean to be rude, but read #10, then some reflection will maybe allow you to see. You presumably must be hard/mainstream left there is a sliding scale before you get to centre, then a sliding scale before you get to far right nut job.
Tories are made up of a load from just right of centre to RWNJ, thats why they are always falling out and having new leaders. If you think of the political scale as being a 300mm ruler with 0 being hard left and 150mm as centre and 300mm being RWNJ, many MP’s will be on a different particular mm to others in their party. The 2 main party’s use the term broad church to reflect that. The British public are the same, most people erring toward centre left and centre right.
Most human beings resist massive change, they fear risk and consequences of upheaval, politics affects all our lives and it is a fact that many people are frightened to have sweeping change that the hard left would bring about asap. Power is only effective with the keys to 10 Downing St, otherwise it is just white noise. Only in power can change begin to be implemented and those frothing at the margins (like some on here) are generally the loudest, but the silent majority are the people that decide the outcome, you have to have peoples trust and will, to go on a journey and it is best done in stages, otherwise you get people leaving in droves along the way and you are back to
