In America, outward anti-Semitism or racism is regarded as part of a lunatic fringe. In interwar Poland, however, anti-Semitism was, in some respects, respectable, and many times in the foreground of political affairs. Anti-Semitism flourished between the wars in Poland because it was easy to scapegoat the Jew, both because it was easy to rationalize and because the Jews were highly visible people then. The Jews, first of all, had very different religious practices, and engaged in them openly, while the Polish were overwhelmingy Catholic. Among all traditional and many centrist Jews, specifically Jewish first names were common, and Jews also had differing surnames. The Yiddish language was easy to pick out, and even the mannerisms, the 'acting out' of language, of the two ethnicities were estranged. Traditional Jews still wore a distinctive dress, and Jewish food is still world-known.
