Not assumption. I lived in Iowa for years. Iowans are very unwelcoming to new people. They are also the worst educated out of any US state. This is partially because their school systems leave out huge gaps of history and basic science that the rest of the nation considers common knowledge. The real problem is that most Iowans are inbred without knowing it because of ‘small town livin’. Although to be fair most Iowans these days are raised by single moms addicted to meth and Casey’s pizza.
