The video is part of a fundraising campaign that went wrong.
Two American siblings decided to rise money for Glasgow as they proclaimed “we are planing to participate with local youth, sharing a message of hope and goodwill with energy and enthusiasm”. According to them “this could turn the situation around” for Glasgow referring to the poor state of the city and the Glasgow effects.
The video went viral reaching the Scots who were angered and offended with the siblings’ description of their city. Most likely they just wanted to raise a money for a nice trip to Glasgow, and maybe volunteering for a bit, but they didn’t expect that their message will reach out the scots turning them into unwelcome guests.
