Just after a shocking mass shooting at a Colorado movie theater that claimed 12 lives and wounded nearly 60 half a month ago, a shooting incident happened on August 5 at a Sikh temple in Oak Greek, Wisconsin, leaving several people shot and injured.

U.S. President Barack Obama denounced the shooting as "senseless act of violence" and said that these terrible events were happening with too much regularity and he vowed to reduce violence.

What's more, Wisconsin police have announced that they are treating the temple shooting as a "domestic terrorist type incident."

It seems that Obama knows very clearly about the standards on "violence", the distinction between domestic and external affairs of a country, and was identified with the persistent annoyance of incidents. But if you further analyze and compare his words and deeds home and abroad, you may find that his standard is changeable, sometimes even as different as day and night.

He always nicely weakens the national differences caused by culture diversity, benefits or class imparity in the U.S., while overemphasizing the uniqueness of one ethnic minority in other countries.

When the shooting in Wisconsin happened, Obama smartly emphasizes the civic awareness and weakens the ethnic differences. "If it turns out, as some early reports indicate, that it may have been motivated in some way by the ethnicity of those who were attending the temple," he said. "I think the American people immediately recoil against those kinds of attitudes, and I think it will be very important for us to reaffirm once again that, in this country, regardless of what we look like, where we come from, who we worship, we are all one people, and we look after one another and we respect one another." In a strong contrast to that, in the statement Obama has made during his private meeting with the Dalai Lama in the White House, he said, "the president reiterated his strong support for the preservation of the unique religious, cultural and linguistic traditions of Tibet and the Tibetan people throughout the world."

Talking of violence, Obama also seems to have his own standards on it.

For average Tibetans, the non-violence strategy advocated by the 14th Dalai Lama appeared to have more to do with hatred and bullying than what Mahatma Gandhi proposed, the power of love and understanding between all.

Even foreign media may notice that despite the happening of self-immolation incidents, the Dalai Lama has failed to demonstrate his "authority" as a "spiritual leader"，and "it is simply a joke to call the Dalai Lama a non-violent person," because "those who died from self-immolation are touted as 'heroes' or 'martyr' by the Dalai Lama and his government-in-exile, which, together with the 'awards' and 'monuments' pushes them to commit self-immolation."

When Obama held 45-minute private talks with the Dalai Lama at the White House, despite strong criticism and strong protest from China that "such an act has grossly interfered in China's internal affairs, hurt the feelings of Chinese people…", did he willfully turn a blind eye to Dalai Lama's tricky non-violence, or maybe he thought that the Dalai clique's conniving on these extreme conducts, which has caused so many people lost their lives, did not reach his standards of "violence"?
