There's a claim often made by opponents of globalization that says it will destroy cultures by somehow forcing our culture upon them, and it's nonsense.

It's not nonsense at all, because it's always backed by a propaganda onslaught called 'advertising.'

Your point is like trying to argue that people chose to stay behind the Iron Curtain. When there's no alternative, when you can't physically move somewhere else with alternative values, and when the media are saturated with On Message slogans peddling conformity of taste and interest, in what sense are people being offered a truly free choice?

Globalisation doesn't work on the basis of 'Well, here's an alternative way of doing things - which part or parts of it are you interested in?' It always comes with aggressive hard sell, and it's this deliberate homogenisation of values that's one of the most insidiously poisonous things about it.
