You both seem to have latched on to the use of the word 'fringe' and weather it's by numbers or seats representation, UKIP is by all counts a fringe party.
Compared to Scotland and SNP party, UKIP is pretty insignificant whatever and however you wish to dress it up.
You really are frothing in the mouth but I don't think either of you know the definition of what it means to be a fringe party.
This is from the same link as one you posted. I implore you to check it out.
Fringe -
4. something regarded as peripheral, marginal, secondary, or extreme in relation to something else: the lunatic fringe of a strong political party.
As for CV, he thinks Farage or UKIP and I'm baffled if there is any distinction between them - is not even a party or have representation in Government.
After all the lies and deceit spread by the Brexit camp, I'm stunned to see so much outrage on a few light hearted quips like "Gang of Four" or use of the word "Fringe" is expressed here.
Altogether now chaps... wheels on the bus go round and round...
