What makes commemoration symbolism accepted—or rejected

Historical significance
UAE issues speech, about Thalassemia disease as a result of marriage of relatives.

Here are the standard criteria for significance:
1. Profundity: How were people affected by the event?
2. Quantity: How many people were affected by the event?
3. Durability: How long lasting were the changes?
4. Revealing: How does this event help us understand the past?
5. Resonance or relevance: how does this event shed light on issues or problems that concern us now?
