AnFi As ever you didn't read what I wrote - the controller protects the IFR traffic by giving clearances to and controlling the VFR traffic - its not rocket science. It is controlled airspace and if you don't like being controlled or think it is 'rude' (FFS) then don't go in it.
Perhaps you should spend some time in an ATC unit so you understand things from their perspective.
Perhaps you should check what the rules are in Class D? In Class D, there is no ATC separation of VFR from IFR. Only IFR and SVFR are seperated from each other. Well that is how it is supposed to be, but of course in good old gold-plating UK it is not in practice like that. Seems to work fine in other countries though.
