All Palestinian children are killed by Israel in their own homes, in their own neighborhoods, or in their own villages.
To say that the Palestinians place their children in harms way is ridiculous and racist.
There is no safe place.
It is the violence of the Arab Palestinians which makes the places unsafe. Nothing else.
Now, if the Arab Palestinians want to use violence to attempt to murder Jews in order to achieve the political goal of dismantling Israel and removal of Jews from their land then they are more than welcome to try.
However, it is incumbent upon them to ensure the safety of their children while doing so. That means removing children from places where violence is occurring or is likely to occur (like the security fences). It means ensuring that military objectives are not placed in houses, schools, hospitals, or mosques. It means not allowing children to participate in activities of violence, and not teaching them to do so.
