am i guilty of gaslighting (re complaints about growiling)

[sort]

DH likes to growl when he's angry. I really hate it.
Also our poor DS is having difficulties with his mental health and emotional regulation, so I asked DH if he'd stop growling because it sets a really bad example.
He told me i was gaslighting him by asking him not to growl. Is that right? Am i invaliding his response to me making him angry and therefore gaslighting?

Have him neutered and keep him in a muzzle.

Jeez, a grown man growling is just weird. No gaslighting here just one v strange man. Does he realise this isn't normal?

@Sparklfairy this is exactly what he said, he growls to suppress his anger and his anger is caused by me.*

Growling is expressing his anger, not suppressing it. Shutting the hell up would be suppressing it. If he thinks growling is suppressing his anger, I worry to think what fully unleashing his anger (at you, the supposed 'cause' of his anger) would look like.
