If I say that millions of people in Lebanon and Gaza approve of Hezbollah and Hamas, I am stating an incontrovertible fact

How do you know this?
In Gaza the opposition has been eradicated, and there is no free press or elections.
Hezbollah may be popular with the Shia, but it is hated by the Sunnis.
It is a violent sectarian terror group.

This thread is about Labour party btw, not Middle East politics.
