We draw the line at violence, destruction, direct harm.

Look I get roads being closed is crap, and you could argue that if they don't allow emergency services through then they're doing direct harm.

A protest isn't supposed to be defined, it is outrage expressed. We're supposed to look and listen and think about how a big enough group of people to be disruptive felt the need.

It isn't tolerated, that's the point.

Note: Blocking roads is directly addressed in Section 137 of the Highways Act 1980 which prevents you from ‘wilfully obstructing the free passage along a highway without lawful authority or excuse’. This police power is often used to remove demonstrators who are standing outside buildings, sitting down blockading entrances or roads and in many public order situations.
