Sorry Lumpy, but they have zero support outside their own organisation. Any thinking person, by definition of being able to think, holds them in utter contempt. They stopped people going to work, left children on streets with no parent to pick them up and blocked ambulances.
I think a few closed motorways for a few days would be a TINY price to pay
if it ultimately coaxed the government (or it's successor) into providing a modern, constructive means tested grant and loan scheme (Upto 馃挴% of cost) for high-grade home insulation and triple glazing.
I mean, they've already done so much damage to their cause that they've not only alienated themselves but made it politically impossible for the government to do anything like what they want. What's next, they start burning tyres?
