I can only assume you are joking/taking the piss. I bloody hope so. If not, yours is the dumbest thread of the week! Of COURSE we won't be stopped from going into Euro 2020. FFS!!! We will still be part of Europe!
And as has been said, plenty of other European countries who are not in the UK play in the Euro Cup!!! (And sing in Eurovision!)

Yep, once Brexit kicks in the moorings which keep mainland UK tethered to Europe will be cut and we’ll be left to drift off into the Atlantic, so won’t be part of the continent anymore. Of course it’s a bit harder with Ireland, but I hear there’s plans afoot to chip off the bit which is part of the UK...
PMSL! 
The scary thing is that some people do actually THINK this. That we are 100% leaving Europe, and we will never be allowed there again, (and probably be exiled from the rest of the world actually!) 
The sad and worrying thing is, that these people voted to remain in the EU, and actually thought they knew what they were doing, when in actual fact, they are clueless as to what the EU actually is!!!
