People are just being wound up to blame others for their problems.
It's the same in tourist locations everywhere, UK, Europe and the wider World. Lots of places in the UK where the locals blame tourists for their problems, whether house prices, closure of shops/pubs, lack of jobs etc.
Same with University towns where locals blame the students for everything, i.e. litter, too many pubs/restaurants, closure of shops, lack of housing for locals etc.
See the common theme developing??
The fact is that shop/pub closures are everywhere, housing shortages are everywhere, lack of decent employment is everywhere, whether tourist location or not, whether University town or not, but people are blaming tourists/students rather than the real reasons of overpopulation, globalisation, centralisation, etc.
I'm on a few facebook town groups and the towns with both tourism and universities are absolutely insane - blaming the state of the town centre on both tourists and students! Completely oblivious to how bad other towns are, far worse, who don't have a tourist industry nor uni students!!
Tourists are just scapegoats because the locals just need someone to blame.
