Probably because of the geographical and different way our governemnts are run. To an extend we have more central government then America so MPs try to appease the total population not just their local area.
The very size of country and how many Americans want their laws and government organized with States rights I think make such issues remain more localised and where there is appeasement as no doubt there is it remains more local.
Yes, where there is appeasement of Muslims in this country now, it is local, but if the Democrats take the House and Senate and Presidency, it will be national policy by this time next year.
