See this map). Given history (see yesterday's post), the fundamentalist Jewish settlements in Hebron will certainly become violent flashpoints as well.
The other, much more frequent, arguments are bullshit.
If the UN General Assembly votes Palestinian statehood it will be repeating what happened in 1947 when the United Nations voted to partition Palestine into Jewish and Arab states. When over 100 nations vote on an issue it is hardly unilateral.

This very small country in a giant sea of hostile Arab nations will continue to be under daily threat regardless of the status of a Palestinian state. With official nationhood status, Palestine may actually have to start bearing responsibility for its actions.
