Yes, a worry Murray and a good reason to stay well clear!

Build an iron wall, mine the border around them, then leave them to practise whatever On their own patch! And entirely undisturbed?

Let them choose whatever for themselves as self-determination and an exercise of completely unfettered free will/religious freedom!

And if covid-19 decides to impose its will there? God is great and showing appreciation for all they do/will or intend to do, in his name!
