Chili monster et al seem to be portraying the same attitude as people who cruise down the right hand lane of motorways. I'm going quickly I deserve to be here.
If the VFR traffic can fly through the chevrons then he is VFR! If you then want that piece of airspace and not to look out the windows - who is displaying poor airmanship? (whilst still acknowledging the VFR trafiic should be talking)
As VFR traffic all you have to do is not bump into the other guy, being routed behind another aircraft is the worst place to be sent due to wake turbulence - my preferance would be almost any other position.
Remember VFR means see and avoid and contrary to many of these wannbes ideas, no one is generally moving that quickly. The only guys you cannot avoid are the military but then they are doing 360 or 420 knots.
The whole gist of this thread seems to be I'm flying IFR and so everyone must give me lots of room and make way for me - don't pretend that is any form of airmanship. Most of what these fora are full of is 'and the other guy then... he should be locked up.'
In this case the other may not have displayed good manners but he probably did obey the rules.
