Sri Lanka underwent almost 500 years of Western brutal colonization, oppression, and suppression of its Buddhist culture, being humiliated and persecuted by Western predator bigots in their own land. It is just natural that Sri Lankans protect their most important asset, specially in relation to what they might perceive as Western abusers.
European countries brag about themselves as examples of freedom, but try to enter any one of them with a swastika tattoo. Or try as a foreigner to enter US or UK with a tattoo which might be interpreted as a symbol of Taliban or Islamic terrorism. Probably you will not be so nicely treated as the British tattooed woman, you will receive a Guantanamo-style terrorist treatment.
And why? Because they see such symbols as a threat to their culture, security, and sovereignty. In the same way the Sri Lankans. But Jewish-Christian Western imperialist brutality is in no way better than Nazism or Islamic terrorism.
Thoughtless Westerners, who can only think what Jewish-controlled press tells them to think, should give up their colonialist arrogance, which wants to set up rules to the rest of the world, specially their ex-colonies such as Myanmar, Sri Lanka, or China, look at the immeasurable damage they have caused to such countries, deeply apologize, and learn to shut up.
