I salute anyone that challenges things they don't believe in by democratic methods. If you can't challenge what your own MP with a strong letter without drawing them into outburst telling you where you can stick your vote....
Given that we the people are the MP's boss, maybe someone would like to tell the MP in question what would happen if we told our bosses where to stick his set of work where the sun doesn't shine
(especially in writing!)
