Whilst I would hardly consider the current COP 26 protests in Glasgow 'irrational' per se, they and others of more recent times don't appear to carry the same shock value as many did pre-mid-2010s, e.g, the G20 protests in central London back in the spring of 2009, of which some even attempted to liken to the second 'Poll Tax Riots', especially where police brutality was involved, plus also the 'Occupy' movements in the early 2010s.
Perhaps considering there's already been umpteen protests over various issues throughout 2021 alone, we're more desensitised to them and as a consequence probably don't find them as shocking as many of such events prior to the mid-2010s, and think 'ah, just another protest', which sadly dilutes the true impact of crucial events like COP 26.
