One rule for the Labour Party and one for UKIP

Before the Brexit referendum, and back when UKIP were performing well in opinion polls,  whenever a UKIP member made a stupid, tasteless or racist comment the BBC portrayed it as symptomatic of the views of the entire party. 

Now when many Labour Party members make anti Semitic comments, and leading Labour Party figures are members of Facebook groups where such comments are far from rare, the BBC suggest that it is just a few individuals and certainly not the entire party.
