Colorado Mass Shooter Father Concerned Son Was Gay ... 'We Don't Do Gay'

The person who committed mass murder at an LGBTQ+ bar in Colorado Springs has not told authorities what motivated them, but if it's what lots of people suspect -- homophobia -- then the apple might not fall far from the tree.

Aaron Brink's first reaction when he learned his son had slaughtered 5 patrons at Club Q ... "I was scared. I was like, 'Oh my god, s***, is he gay? And he's not gay,'" Brink told a reporter sighing with relief.

He wasn't done ... Brink said, "I'm a Mormon. I'm a conservative Republican and I don't do gay. I don't do gay. We don't do gay."

Anderson Lee Aldrich says they're nonbinary, but not everyone believes them. Several friends have come out and said they never even hinted they were prior to the murders. Some believe they're saying this to avoid being hit with hate crimes in addition to murder and other charges.

Brink, who is a porn star who goes by the name Dick Delaware, did express remorse for what his son did ... "There's no excuse for going and killing people. If you're killing people, there's something wrong. It's not the answer." he went on to say, "I'm so sorry for your loss."

It's unclear when the 2 became estranged, but Brink says Aldrich got a name change after he became involved in porn. He also said he was falsely informed by his ex-wife Aldrich committed suicide in 2016.

Aldrich has been charged with five counts of first-degree murder and five counts of a bias-motivated crime causing bodily injury. They appeared in court for the first time Wednesday with their face battered and bruised from the beatdown they received from heroic patrons who disarmed and restrained them.
