How about the tactic of talking utter cobblers, and instead of providing proof defending the cobblers, continually asking someone to get busy wasting their time finding irrelevant specific counter examples, whilst those playing the tactic sits back and enjoys their little game, all the while ignoring the obvious facts already presented regarding the EU rules/laws ?
It's fooling no one, and it got boring a long time ago. One should defend a view in the face of opposing evidence if one wishes/can, or not; but not keep asking for more and more evidence simply because one has no answer and wishes to hide the fact.
