Whilst I agree with your campaign and I also agree with writing to your MP I cannot agree with the emphasis you place on IFR operations being safer than VFR operations.
I think this creates a very misleading impression with people who are less well informed about avaition matters and suggests that the vast majority of pilots who operate VFR are dangerous.
Moreover I think your assertions are dangerously wrong - I am not aware of any evidence to support your argument.
As an instrument rated pilot I believe the point that should be made is to operate in Europe for business which by definition requires running to a reasonable schedule then a pilot can only operate safely with an instrument rating - quite a different matter.
