Joseph: My first attempt at this wasn’t approved, so I’m going to try again.
When Jews move to an area, they tend to build larger homes and more of them. This is because we tend to have more children, and our communities also tend to draw other Jews there. While this can have a good effect on residents by causing home values to rise, it also changes the character of a place. What was a quiet town, with ample parking and little traffic, can become a busy area. Many residents don’t want that. They like the quiet, not having to search for parking, and little traffic. When Jews move to an area, things don’t stay like that for long.
Due to private Jewish schools opening, and Jewish residents wanting certain services for their children (special ed, busing, etc.), either the taxes would go up, or the funds available to the public schools would get cut. That’s another thing the non-Jewish residents want to avoid.
So do they not want Jews? Possibly. But it’s not anti-semitism. It’s just that they know what it means to have Jews start living there, and what it would do to the area.
