A Connetquot school board trustee apologized Tuesday night for posting an expletive-filled rant on his Facebook page that called for killing mentally ill people and punching President Barack Obama.

The board member, Ted Imbasciani, told an angry audience of about 200 teachers and others that he had not paid close attention to the words he dictated into his Facebook page. He said he had been upset at the time over recent college campus shootings.

Much of the rambling post dealt with Imbasciani's personal opposition to stricter gun-control laws.

"I apologize for getting everyone so riled up," said Imbasciani, a former New York City police officer and local civic leader who was elected to the board in 2013. "I hope that's enough."

Imbasciani did not directly address calls from several speakers for his resignation, saying he would check with the district's attorney before deciding his next move.

Imbasciani wrote the controversial post earlier this month and later removed it. It used repeated profanities, cited "liberal idiots such as educators" and called Obama "evil."

Tony Felicio, president of Connetquot's teacher union, was among a half-dozen audience members denouncing the post. "We found it offensive and very concerning at a time when we want to emphasize that students not bully, not take action that leads to violence, that a board member could write such distasteful things in a public page," Felicio said.Several residents who rose to say they supported Imbasciani's right to his opinions, though not necessarily the opinions themselves, were jeered by the rest of the audience.
