If you read the post its saying that both sides lunge to the left and right is creating the very beasts that head up these parties .
It's generally accepted that it's not nice politics anymore, from either side , these extremes are putting awful people in charge of these parties and as each one spouts its hatred , it fuels the wrong type of politics that decent people like and want .
So many people feel lost , with no real party to attach themselves too, and that includes some very long serving (decent ) socialist.
