A teenager known for anti-Israel sentiments and boasting nearly a million followers on social media stirred up controversy on TikTok by urging people to “support” the suspect in the DC Jewish Museum killing. This action led TikTok to take the unusual move of swiftly removing the post.

Guy Christensen, a 19-year-old from Pennsylvania who often wears a keffiyeh and is known online as “YourFavoriteGuy,” reiterated his views in an interview with The Post on Friday.

“You will not hear me sympathize with war criminals,” Christensen stated over the phone, referencing the two Israeli Embassy diplomats who were allegedly killed by Elias Rodriguez, an accused anti-Israel gunman.

Christensen — in a TikTok video Thursday that garnered more than 632,500 views before being taken down — said, “I want to urge you first to support Elias’ actions.”

In his video, Christensen added, “I do not condemn the elimination of those two Zionist officials who worked at the Israeli Embassy last night … and here’s why.

“Israel has a live-streamed a genocide to the entire world the last two years,’’ he said.

“You can not expect to do such a thing in this world without the people standing up to fight to stop you in any way they can, to resist against you,’’ said the college freshman, who refused to say where he goes to school.

Asked by The Post if his post could be interpreted as saying he supports the killing of the victims, the teen replied, “I think the only people who are interpreting [that] as such are the people’’ who are using the slayings of “those two Zionist officials … as a pretense to silence critics of Israel.’’

Christensen — who has previously indicated online that he is from Pittsburgh — called the dead man, Yaron Lischinsky, 30, a “war criminal” in the footage, which included a Palestinian flag in the background.

“And the same was true for the woman,’’ he said, referring to Lischinsky’s dead girlfriend and soon-to-be fiancee, Sarah Milgrim, 26.

He meanwhile insisted Rodriguez was “not a terrorist.

“He is a resistance fighter,’’ Christensen said.

He added to The Post, “I think it’s very shameful that the media would rather cover Elias Rodriguez over the death of hundreds of Palestinians yesterday.’’

TikTok still had Christensen’s inflammatory video up early Friday afternoon.

A rep said in an email about a half-hour after a Post inquiry about it that the footage was taken down “for violating our Community Guidelines.’’

“We have removed the video that you shared for violating our Community Guidelines,’’ the representative wrote.

“Our Community Guidelines prohibit anyone from promoting violent or hateful actors, and we do not allow conspiracy theories that are violent or hateful, such as denying well-documented violent events.”

Christensen told The Post that his video had been initially taken down by TikTok, then he appealed and won. After it went up again, it was taken down again, and he appealed and succeeded in his bid.

He said it was taken down a third time and that there would be no appeal.
