You seem to have an odd idea of what 'treason' is or means. And you obviously dislike democracy, too. Not doing too well, are you?
Many people voted against brexit. Not surprisingly, they are still against brexit. That's treason?  Obviously not - it's keeping to an opinion which is looking more and more correct because many who voted for brexit have changed their minds. And May is doing nothing to help the situation by pretending a hard brexit is good fro UK. Good for the EU maybe, but certainly not for the UK..
