Explanation: How the watermelon 🍉 became a symbol of Palestinian protest 🇵🇸

It's especially relevant now, because Meta (i.e. Instagram and Facebook) is hiding posts and comments containing the Palestinian flag emoji, and people are turning to using the watermelon emoji as a substitute.

As an aside, the Jordanian flag emoji 🇯🇴 and the Western Saharan flag emoji 🇪🇭 are visually similar enough to the Palestinian flag emoji to be good substitutes.
