Why is the dragon the symbol for Wales?

The dragon, imagined as fiery, fearless, powerful.

So why is it the symbol of Wales? A passive, subservient nation.

A bit of a bite 600 years ago perhaps, something the few activists still hang on to, but since? 

The nation that stood by and watched people forced from their homes and a valley flooded to provide water for English cities.

A nation that accepts that Scotland [ and England of course ] can have more power and control over their lives than Wales, under the same system of devolution.

A nation who accepts the austerity, poverty, poor health and social care, poor education, poor housing and poor local services, because of a constitutional system imposed by an affluent elite in Westminster 

A nation who constantly and blindly elects a government party in Wales, who support the system at the root of this deprivation.

The other symbol of Wales is the leek.

 Now that's more like it. A mild bunch of vegetables.
