How does a Theravada Buddhist show he is Buddhist?

Answer:
The best way to "prove" your Buddhist sincerities - I'd say - is to teach someone else what you know about what you do know.
There is no magical meditation they can use to levitate in the air, nor do they need to shave their head and wear a robe. They don't need to expound 2,500 years of Dharma in a continuous stream of information nor recite mantras in perfect Pali with the appropriate mudras.

If I say I know how to play the guitar I will prove it by playing it. If I say I am Buddhist I will prove it by being Buddhist and teaching what I have learned.
