Brandi Glanville knows she’s wading into dangerous territory talking about Kim Zolciak‘s 15-year-old son … and she’s admitting she’s being a hypocrite for doing it.

Brandi addressed the allegations against Kroy “KJ” Biermann Jr. on her “Brandi Glanville Unfiltered” podcast … saying she normally believes underage kids shouldn’t be dragged into the spotlight just because their parents put them on TV.

But she says this case struck a nerve because she’s a mom of boys.

Brandi said she drilled consent into her sons growing up … telling them they couldn’t even hold hands, kiss or hug a girl without asking first.

She also acknowledged the irony of discussing KJ publicly, saying … “I’m realizing I’m a hypocrite, because I’m saying we shouldn’t talk about kids that are underage, but I’m sitting here talking about it.”

As TMZ previously reported … KJ was arrested earlier this month and charged with aggravated sodomy and aggravated sexual battery after a female classmate accused him of sexually assaulting her inside a gym changing area.

Kim has vehemently denied the allegations on her son’s behalf, telling TMZ he “categorically denies” the alleged conduct and claiming he passed a polygraph examination.
