I can sympathise with the general view that JSO are fking annoying in the manner of some of their protest and that their tactics are probably not helping solve climate emergency.
But then I also sympathise with the view of JSO that politicians and big business are doing virtually nothing to counter the climate emergency, simply kicking the can down the road and spouting a load of hot air when the time for radical policy is right now.
In 100 years, JSO will be the tiniest of footnotes on articles and books regarding the effects of climate change in the 21st century, while 99% of articles will focus on politician inaction, corporate greed and corruption, mainstream media silence (again, follow the money), and the devastating effects of what we considered as the reasonable status quo.
JSO will probably be viewed historically as an ineffective fringe protest group with questionable tactics but correct in their views. The Mail, the Sun, and the rest of the media and political establishment advocating head in sand policy will be viewed 1000x more harshly.
