As a so called 'remainer' (or 'remoaner' if some of 'you' would prefer), I too had no particular objection to someone referring to Tusk and Barnier as 'Arrogant Gits' in a recent post. I simply don't agree with the poster's viewpoint. I don't particularly like Barnier's demeanour at times myself, but Tusk and Barnier are just doing their jobs, and are understandably sceptical about the British negotiators' stance on the Northern Ireland situation. The UK has simply not put forward a proposal that can possibly work.
I agree with what you're saying but just a point of order
It's true, the EU negotiating team, which include Tusk and Barnier, have shown excellent integrity, intelligence, and patience protecting the interests of the EU which includes us in the UK because we are also a member of the EU at this moment in time, and bearing in mind the majority of UK people really want to remain in the EU. So we are fortunate to have them represent us against some pretty ugly 'British' political types who claim to represent 'us'.
The so called 'British negotiators' representing the so called UK are noting but a rag-bag bunch of fanatical Brexit Tory Political Party gang of hardened liars and greedy financial opportunists with a mandate to represent the interests of a particular nasty UKIP inspired future Tory Party Political dogma, even though this is clearly not and never has been in the UK national interest or the will or the people of the UK.
Us, Our, We, ...the peoples of the UK do not have any Brexit representation from this corrupt Tory government team of double-dealing back room secret negotiators, and that lack of representation also includes people who voted Leave because IF they [ them ] in the Tory Brexit Party ever do get their way and succeed in breaking ties with the EU, the new Brexit Bonkers World Order UK will be just as much a disaster for them as it will be for the majority of us.
