A number of anti-Israel social media accounts have posted how Israeli teens lynched another teen because he looked Chinese; Accounts such as VPalestine:

and DouchebloggerTM Richard Silverstein:

But there is absolutely no report to suggest this is why the teen was murdered. In fact, the report to which Silverstein actually links suggests – like all the others I have seen – that he was murdered in a brawl.
The police in Israel have arrested eight residents, all between the age groups of 13 and 15 for stabbing an Indian-origin teenager to death at a birthday party in the northern city of Kiryat Shmona, local media reported.
Yoel Lehingahel, 18, had emigrated from India less than a year ago with his family to Nof Hagalil, a city in the Northern district of Israel. He belonged to the north-eastern Indian-Jewish community of Bnei Menashe.
Besides a 15-year-old resident of the nearby Chatzor Haglilit town, police have detained seven more youths, all aged between 13 and 15, the Times of Israel reported.
A fight involving more than 20 teens broke out at a birthday party which was attended by Lehingahel, Meir Paltiel, who works with the community of Indian-Jewish immigrants to Israel, news portal Ynet reported.
In a Facebook post, Ronen Plot, Mayor of Nof Hagalil, described Lehingahel as a “happy” boy who had expressed his desire to join an IDF combat unit.
“A whole life cut short because of an act of violence, which in my eyes was an act of terror in every way,” Plot said.
Lehingahel was a member of the Bnei Menashe Jewish community that has been immigrating to Israel over the past two decades from the north-eastern Indian states of Manipur and Mizoram.
While murder is a murder and this is a blight on our society, to paint it as a racist attack against Chinese is not supported by any news reports. The fact VPalestine, Silverstein, and others readily disseminated this lie shows their bigotry – not just against Jewish Israelis, about whom they will readily lie in order to demonize – but also Bnei Menashe who they are comparing to Chinese people in inventing the lie to begin with.
By the way, these are the same haters who vehemently oppose the Bnei Menashe returning to their homeland:

and support the murder of all Jews in Israel as legitimate “resistance.”
And not many haters are more racist than Richard Silverstein:

@weinstein_g I called her "Negro Zionist" and "Uncle Tom." She's no slave coz she's paid 2 do what she does. Also, she's a willing flunky.

Southern slave owners had their House Negroes. Israel's MFA has @RashaAthamni to promote Brand Israel.
