The things people are protesting against now are pathetically trivial compared to the things those people protested, that’s why.
They’re more just a bunch of people don’t like something, or are against something that they think is happening when it actually isn’t (or is at least a 50/50 issue).
There’s also the fact that most of the protesters these days are just virtue signallers, or are rent-a-protest paid protesters who couldn’t care less.
Just go sign up for any of the activist organisations that advertise it:

Did you really think that the protests that are 90% pensioners holding all the same print signs and chanting the same thing, often reading from their printouts they were given, were organic?
