I would just be thankful that you are allowed to re-enter the country if I was you and stop complaining. Boris is dammed if does & dammed if he doesn't. Would you want to be the person that gets up and say "Sorry no Christmas this year". If you want to blame anyone, decide who/where this all started and blame them. Unfortunately C19 is here, brought in by travelers who had it and we now have to combat this together taking the advise from our PM and his team working with him. We will all be able to have our say when its over,
My final point is that no-one has any idea of what will be the final outcome as we have never in the past had anything like this in the past. Yes we had the Black Death but this took years to get here, Spanish Flu after WW1 took time to spread (and did not infect the whole planet). This one spread out of control very quickly mainly as we can get around by flying etc.
So far I have lost a brother in-law to it, and my sister and my son are both still suffering the long term effects have had it. Just be thankful still to be here.
