LOS ANGELES – Actor and activist George Takei presented a petition to a leading American Muslim civil rights group, which contains over 300,000 signatures of people showing solidarity with the American Muslim community.

“I have spent my life trying to ensure something like this never happens again,” Takei wrote on the petition cited by Los Angeles Daily News on Monday, February 13.

“National security must never again be permitted to justify wholesale denial of constitutional rights and protections.”

The Star Trek actor went to Los Angeles City Hall Monday evening to speak out in support of Muslims in the United States.

Takei wrote about his own experience in a Japanese internment camp as a child during World War II in the description of his Care2 petition.

His firsthand knowledge shows where bigotry could lead.

“A Trump spokesperson recently stated the internment of Japanese Americans during World War II “sets a precedent” for Trump to do the same today.

“And Trump continues to stand by his plans to establish a Muslim registry and ban immigrants from “certain” Muslim countries from the US It starts with a registry, with restrictions, with irrationally ascribed guilt, and with fear. But we know well where it might lead.”

Takei was joined by Los Angeles Mayor Eric Garcetti and other city officials at the event.
