They view the atrocities as having occurred to strangers in a faraway place and so fail to see how they will affect Sighet.
Explanation:
Elie Wiesel's memoir "Night" is a recollection of the atrocities and discrimination that he and his fellow Jews faced during the Nazi regime. This book serves as a memoir to show the experiences and provide a first hand account of the Holocaust.
The Jews In Sighet were not really concerned about the atrocities done by the Nazis elsewhere. When Moshe the Beadle, who came from a different part of the country, told them about the discrimination that was done by the Nazis, they refused to believe and did not even care about it. Rather, they view it as having occurred to strangers in a faraway place. They also fail to see how these actions will affect or reach Sighet.
