It's not being meek, it's being patient and resilient.
I'm French and I used to live in the UK for a while. There is a very strong difference in my experience between going on strike about twice a year (I'm on strike today!), and absolutely never demonstrating and rarely complaining publicly about deep social issues.
The list you provide is actually not very impressive by a lot of other countries standards. I don't mean it in a demeaning way: there are other levers for social progress, and no country uses them all. But massive social action is not something that the Brits use very often in my experience.
