If you came to the UK, and I welcome you to, you would see that the anti-israel group is a minority, that anti-israeli policy is not the same as anti-semitism. And you would see two things:
1-the UK dosent care about Isr vs Pal: we are sick of it.
2-the British are not and never have been an antisemitic nation, quite the opposite. The least antisemitic nation in Europe. And no more than Canada or America.
BTW, Muslim majority?. Why do people here think the Muslims are gonna take over?. 5% of the UK is Muslim. 95% isnt and 92% of the UK is white.
