I was wondering because my teacher said that Jewish people scratched the walls and left marks, but I read that it is not possible and got in trouble for questioning her. Can someone actually tell me because I cannot find a reliable source to show my teacher. Can someone explain it to me and/or give a reliable source?
Hi there -- you may be interested in this long post by u/commiespaceinvader about the same question, in an older thread:
Where did you read that it isn't possible?
