Should Britain give up the ghost and relinguish all soveriegnity to E.U and immigrants?

It just seems so absurd that we draw red lines under certain clauses of the Lisbon treaty which fall away in 5 years time, allow all these immigrants yet maintain an air of anger and tolerance.It's absurd. Either we accept our politicians manipulations and the way it is or we pull out now and retain who and what we are/were.
