It makes sense because if we take away the focus of Islam as a religion and just look at what they espouse, there is little difference between right wingers and extremist Islamic groups. Islamic groups just have that bit extra flavour.

Honestly I think protestors/political parties could point this out and get a tonne of support because so many Normie's would kick up more of a fuss over this than brexit. Sigh.
