Suspected Austin package bomber Mark Conditt decried gay marriage, abortion and registries for sex offender in a conservative blog he is believed to have authored in college.

Austin police announced that the suspected bomber who blew himself up early Wednesday as authorities closed in on him was Pflugerville resident Mark A. Conditt, 24.

In the “About Me” section of the blog, the writer identifies himself as a Mark Conditt from Pflugerville, Texas. Officials haven’t independently confirmed him as the author but only one person by that name lives in that city, according to public records.

“I am not politically inclined. I view myself as conservative, but I don’t think I have enough information to defend my stance as well as it should be defended,” the bio reads.

The site, called “Defining my Stance,” was written by a Mark Conditt for a class on US government at Austin Community College in 2012, a former classmate told The Post. Twenty-three students were listed as having blogs related to the class.

One of the students, McKenna McIntosh, said she remembered taking the class with Conditt, who she immediately recognized.

“I remember him and being in class with him but not his blog specifically,” she said.

McIntosh, 26, said she started crying when someone sent her the image of Conditt from his mother’s Facebook circulating in the news and she realized what he was accused of.

“I can’t believe I was even within reach, at one point, with someone who is capable of these acts,” the mom-of-one said.

A spokesperson from the college confirmed that Conditt attended between 2010 and 2012 and did not graduate.

The six blog posts were written between February 2012 and May 2012 and take on topics like internet piracy and whether to release terrorists.

In the post on terrorism, Conditt argues that al Qaeda operative Majid Khan — who was charged with five war crimes — should “get a life sentence twice over.”

A pro-death penalty post reads: “Living criminals harm and murder again — executed ones do not.”

Conditt also posited that the US should do away with sex offender registries because “you have to really hate the guy to make him suffer for the rest of his life, even when his prison time is up.”

“So you have a guy who committed a crime,” Conditt wrote. “Will putting him on a list make it better? Wouldn’t this only make people shun him, keep him from getting a job, and making friends? Just for a crime that he may have committed over 15 years ago as a adolescent?”

In his anti-abortion and gay marriage posts, Conditt argued that women should only have sex if they can provide for a child and that it was “not natural” for people of the same gender to be together.

Austin police said they believe a suspect named Mark Conditt fashioned all the explosive devices used in the bombings that have rocked the city since March 2.

They warned residents to remain vigilant as Conditt may have placed more bombs that have yet to go off.
