I almost wonder if the problem was Chris. Kids are weird with touching other kids sometimes, and Chris has shown he has no problem touching people inappropriately in his later years.
It could also be why Barb's family never wanted them around, and Chris spinning it as they didn't like Barb being a hussy, yet there's pictures of the 1980s where both Bob and Barb are at some kind of family get together. I don't think David Chandler ever introduced or let them over with his daughter. Chris only ever talks about a handful of other kids he's played with when he was younger and not being locked in his room. That's kind of strange, he never talks about hanging out with the neighborhood kids, just 100% girls that his parents set him up with. Maybe they were frightened that if they had him hang out with other boys, he'd touch them or something?
Speculation time! Maybe Chris had it drilled into his head not to do that "homo crap" because it's the worst thing in the world, and Chris decided to project that on the handsy principal at Nathaniel Greene elementary school. It could explain why Chris absolutely hates homosexual men, where as you'd think he might like some of the community's feminine mannerisms.
Honestly given his weird sexual deviancy, especially right now, I'm not willing put anything past him.
