I ran across this awhile back, sound familiar?
The Gypsies also faced prejudices about their way of life. The Gypsies' travelling lifestyle aroused suspicion because of the common belief that "itinerancy served merely as a cloak for a deviant range of predatory, parasitic, and criminal activities" (Mayall, "British Gypsies" 8). People were distrustful of Gypsies simply because they moved around a lot. Accompanying this mistrust was "a belief in the superiority of the settled over the nomadic culture and the incompatibility between the two" (Mayall, "British Gypsies" 8).
