As I've said elsewhere, lobby who you like but press the jobs,growth and investment buttons each time and present as a positive person with good ideas to make the country better.
Elaborate Tales of grievances, injustice and unfairness, no matter how real, will simply get you labelled as a whiner, especially if you wave an AAT case in their face and invite them to read it. They don't have the time to right all your wrongs.
