am i a snob for saying this?

I am seriously hoping that even though I am not from here, I do not stick out like a sore thumb. After seeing the American\ Canadian\ English speaking tourists that walk by I am almost embarassed to be associated with the English language at all. Seriously, they are so loud and obnoxious... like they demand everyone to pay attention to them as they walk by. They even have the nerve to become angry when they are in a restraunt ordering in English and the servers do not understand them. 'Do. you. not. understand. i. want. pizza. mar-gar-it-aaaaa' I have trained myself to talk quieter and to do my best not to laugh obnoxiously at all the wrong times or become upeset when i am not understood. I like to think that we are doing a good job blending in. I know a few people have thought we were French... but that probably is caused by that fact that I still keep speaking French to everyone accidently. When i do get the Italian right, i still get it wrong. I say 'Gratzi' when i am trying to say hello. I feel so mixed up... I'm confusing English with French and Italian with French and French with English. Oh boy
