As previous posters have stated, we have this kind of sectarian behaviour every year in N Ireland - flags of countries and pictures of politicians are burned on bonfires because the bonfire attendees hate them so much.
It's so strange seeing the growth of sectarian politics in GB when, for decades, things like this mostly only happened in NI as a result of our fractured/divided society, and the majority view in GB was to view us as a bizarre, regressive outlier within the UK/Ireland.
I wouldn't wish this type of politics on any country because it never achieves anything positive and it always ends up with people being killed for their political beliefs or their background. It leads to us not seeing other people as human.
