ELI5 the hate for Jews

I could never really understand, I wouldn't even really be aware of their existence (except for that little thing hitler did).

In general, throughout history, Jewish people have been a very tight-knit community.  This means that when a group of Jewish people moved to a new area, they would retain their Jewish traditions for the most part rather than completely adopt all the traditions of their new neighbors.  

This strong sense of Jewish identity sometimes made their new neighbors feel like the Jews were stuck-up or strange.  Then, if something goes wrong in society, the citizens are going to look for someone to blame and if they already have a small minority that acts different from the group then it becomes easy to pin the blame on the Jews rather than really address the true causes of whatever went wrong.  Of course, sometimes Jewish people did cause problems but a lot of times they didn't cause problems but still got blamed just because they were a little different.
