You're having a go at someone else for toxic masculine 'it'll be all right language'
? Chuffing hell. This is mindless hypocrisy from yourself. You could just as easily be swapping places with different views with Skipdriverjohn.
You're also talking complete nonsense yourself. In March Skipdriverjohn would have been very unlikely to have been given a test. Higher quality antibody tests along with many others besides were also taken off general sale by PHE and I don't know whether they've returned. You can in theory get hold of the lower accuracy ones, but antibody tests of repute are generally reserved for studies and workers.
Three recent pieces of research also suggest, that if he did have it in March he may test antibody negative now anyway.
