Well it’s not that simple as ‘this generation’ because if anything - issues like BLM, Insulate Britain etc has shown, is that ‘this generation’ does have an appetite for protests - but when it inconveniences the wider population then support quickly wanes. People were frothing at the mouth at protestors who were insisting the government do more to make homes better insulated ffs.
And ultimately it’s not down to the younger generation to protest on their own because it’s not like that’s the target voter for this government anyway. It’s the Gen X’ers & Boomers who should be on the streets, because they make the majority of their voter base and they’re more likely to listen to them.
But at the same time, this quick dismissal of social media as something that exists in a vacuum and isn’t part of reality or doesn’t have an effect is so dated too - anyone who continues to play down the impact of platforms like Twitter (when used properly) is way behind the curve. You only need to point to Rashford pressuring Boris into a U-Turn as an example of social media pressure applied correctly.
