Why should Farage hold his head in shame? He has always sang the same tune.
This is true, he did sing the same tune. But why? Was it for the good of the British people? No. Was it for his own ends? Yes.
How would he know that the EU was a good or a bad thing? He rarely went to any meetings.
He was disingenuous in stating that the EU foisted laws upon the UK. If he'd attended more often, he'd know that there needed to have been a unanimous vote for any law to have been applied, so even him voting against any proposal would have been enough to stop it, if he'd been there.
He would also have known that the UK had one of the lowest rates of acceptance of migrants and that there were even more options available that the prevailing government chose not to leverage, had he been there.
And why didn't he step up with his plan to say "Right everyone, we've won, here's what we do." But he didn't have one because he's just a disruptor without a plan any further than "this might do me some good".
Oh, and you'll note that he collects his £73k EU pension and didn't say anything along the lines of "I didn't agree with the EU, so I shall pass on the pension that I get without ever really having attended".
That's why he should hang his head in shame. Oh. Along with all the other bullshit of why leaving would be so good.
