Guardian likens Hamas rockets to "useless fireworks"

The Guardian, in an official editorial on the war in Gaza, argued the following:

In all the years they have been swooping over the border like useless fireworks, the primitive rockets that Hamas fires at Israel have killed hardly anybody. They scare people, close supermarkets, disrupt business and increase insurance premiums.

They’re of course referring to the more than 15,000 deadly projectiles fired from Gaza since 2001.
Here is the arsenal of “primitive rockets” the Guardian is referring to:

Here’s a glimpse into the effects of the “useless” fireworks” “swooping over the border” to the southern Israeli city of Sderot:

Contrary to Guardian claims (that “hardly anybody” has been killed by these “useless fireworks”), at least 20 Israelis have been killed in Gaza rocket attacks since 2001, and 15 have been killed in Gaza mortar attacks. (sources: here, here, here, here, here, and here). Over a thousand Israelis have been injured in such attacks.
Finally, every Gaza rocket (all 15,000) of course has the capacity to kill an Israeli man, woman or child, and all represent an attempt to do just that.
Describing such deadly instruments of war as “useless fireworks” (which have killed ‘hardly anyone’) is simply untrue, and grossly insensitive to Israeli victims.
