I am an Eu citizen and resident, and remainer.
I agree the EU cocked up yesterday. It was an own goal, ill thought through, a knee jerk reaction that they should be ashamed of. However they backed down very quickly when one minor country of the 27, Ireland, told them to. That shows reason and the ability to say, OK, we went too far. Don't see that much in Westminister.
However I think they have been royally screwed by AZ so are right to be upset.
I also think the vaccination programme is too slow in the EU but, at least in EU countries it is slow but following the guidelines for the 3 week gap between jabs, which is safer than the 3 months going on in the UK.
However, the anti EU rhetoric being whipped up in the UK press is appalling, and very much to distract from the devastating way the UK has in general handled the pandemic. Some of the comments show a staggering lack of knowledge of contract law and a simplistic bias of UK vs the funny foreigners across the Channel.
Anyone who is using the misjudged attitude of the EU this past week as an argument for Brexit or an exit of their own country from the EU is not thinking it through.
Personally I am happier in a flawed but on the whole democratic EU than a corrupt and greedy UK run by the most inept government in recent generations.
