Like all news organisations the BBC gets views based on outrage and I don't think the Greens or the Libdems get 1/2 Farage's news coverage based on having 1/2 his support and that's clearly because they don't do outrageous things.
They pretty consistently just want a 23rd arab state, want all the Jews gone, don’t care about the 850K jews forced out of other arab states, and don’t think Jews are native to Judea or that Arabs come from the Arabian peninsula.
