I'm going to troll americans while on holiday
What makes you want to troll americans while on holiday?
They are a crude set of people.
I understand that you may not like how Americans act, but it's not okay to treat them badly. Leave the Americans alone and deal with your own prejudices against them instead.
They call me a piece of shit in the chat.
There are many Americans that hate each other and it is based on stereotypes and political leanings. Don't assume that all Americans are the same, because many of us are embarrassed over our neighbors too.
