US President Barack Obama may face a hostile Christian crowd when he visits Roseburg, Oregon, on Friday to condole with the families of the victims of last week's shooting rampage at Umpqua Community College.

Angry residents said Obama is not welcome in their town after he displayed "total disdain" of the Christian community in Roseburg when he hastily called for a press conference at the White House not to condemn the killing of eight Christian students and their teacher but to promote his gun-control agenda.

Leading the Obama bashers in the Oregonian town is David Jaques, the publisher of the conservative newspaper the Roseburg Beacon. Jacques said the president's trip is "very inappropriate, and I think it's disrespectful to the families."

Speaking to Breitbart News, Jaques derided Obama for his decision to hold a press conference right after the shooting and for what he said and did not say during that press conference.

"We haven't even identified bodies, we've still got incident command trying to contain the scene, and he's holding a press conference 3,000 miles away from here, telling—almost implying that he could have single-handedly prevented this if the Congress would have listened to him," Jaques said.

The newspaper publisher said he believes the real purpose of Obama's visit is "to take away Americans' right to own firearms."

In an interview with Mediaite, Jaques also accused Obama of wanting to "stand on the corpses of our loved ones and make some kind of political point."

Killer despondent for having no girlfriend

Meanwhile, the 26-year-old gunman who mercilessly executed eight of his classmates and his professor inside their classroom before killing himself appeared to be grappling with an emotional crisis before the shooting.

This became apparent after a law enforcement official revealed on Monday that Christopher Harper-Mercer complained about having no girlfriend and feeling like everyone in his class was crazy in the writings he left behind, a TIME report said.

"Other people think I'm crazy, but I'm not. I'm the sane one," Harper-Mercer wrote in one of his writings, according to the official who requested that he not be identified.

The official also revealed that the killer's mother had told investigators that his son was struggling with autism.

Gunman's mother a gun lover

In a related development, Laurel, Harper-Mercer's mother, revealed herself in her many online posts that she is a gun lover and that she allowed her son to use the guns in target practice despite his autism woes, according to the Daily Mail.

In several online posts, Laurel talked about her love of guns and her son's autism symptoms. However, she seemed unaware of her son's emotional problems.

In fact, she expressed pride in her son. In one post, she wrote: "He's no babbling idiot nor is his life worthless. He's very intelligent and is working on a career in filmmaking."

Harper-Mercer and his mother lived in an apartment outside Roseburg. The two used to live in California together with Harper-Mercer's father before his parents divorced when he was teenager. After the divorce, Harper-Mercer and his mom moved to Oregon in 2013.

Harper-Mercer's father, Ian Mercer, still lives in California. Last weekend he expressed shock that his son had so many guns found in his possession.

"How on earth could he compile 13 guns? How could that happen?" Mercer told CNN on Saturday.

Investigators recovered 14 firearms—six found at Umpqua Community College, where the killings occurred, and eight at Harper-Mercer's apartment.
