Politics has been dominated for years by professional politicians whose main aim has been developing their careers. To that end they have steered clear of controversy. Corbyn has held controversial opinions throughout his political career and suddenly people have voted him in as leader of one of the main parties. That landslide victory carries a message for all those who have spent years being mealy-mouthed and toeing the party line. People are sick of it. They want commitment and honesty.
Younger people today are different also. The left have traditionally been defeated by name-calling (loony left etc). Younger people are likely to call that bullying and they won't like it, just as they didn't like it when it was tried on Farage. Those wishing to defeat Corbyn are going to have to dust off their brains and defeat him by using factual debate rather than soundbites. They are going to have to justify their policies and beliefs sensibly. Do they have the brains after so long of letting them lie fallow? We shall see.
The Tories have declared war on the young, whether they're working, studying, or do something else instead. (New Labour did start the process though.)
In fact they've declared war on every group, except drivers and the retired (both groups being too powerful to take on).
You're right, the young are thinking differently to the rest of the country. They've have had enough of being made to pay for the mistakes/greed of the financial institutions. It was their votes that elected Corbyn.
