"Just Stop Oil"
Errr, and replace with what exactly?
Oil is used in so many products it is impossible to just stop.
Oil will have been used in the manufacture of the trainers on the protestors feet, and looking at the woman's jacket, most likely in the production of that as well.
If they're that committed to their cause they should ensure they have nothing to do with any product where is oil is used, but of course they won't, because (a) I'd suggest it is virtually impossible to do so, but (b), even if it was possible, people like this tend to be hypocrites.
