No, that isn't common either. I'll ignore the fact that it has nothing to do with what I described. It's something else entirely.
The stereotype you probably mean is American's going to a country, ignoring their language and customs and then declaring their way the correct way.
Something isn't a stereotype because you just deem it so. The way the topic is presented was stupid. And I see many topics that paint one state in a negative light like everyone in that state is of some hive mind. It's dumb. I am not even defending Texas. Texas has it's issues too. If anything I am attacking people who love stereotypes...so I guess that means you too.
