You are quite something.
Earlier on, you yourself wrote:
"FWIW I think these kinds of protests are doing more harm than good"
Personally, I think addressing climate change is critical and within that, properly insulating homes is a big win.
However, this protest won't help, as you acknowledged yourself an hour or so ago. But now, because I object to people doing unreasonable and dangerous protests I am somehow in support of the South African apartheid government? wtf like!
Your logic is whack, but it doesn't seem like reason is your thing.
Go and ruin someone day on the M4 if you feel strongly about it. Telling me I want to imprison Nelson Mandela isn't helping until such a time that we can harness hot air generated from messageboards.
