You seem to have missed the part where I said “unless there’s imminent danger”.

Nope. Yelling isn’t okay. Parents are human and may do it anyway, but it’s always a mistake and should be treated as such (except in the case of danger as mentioned above). It absolutely should be avoided as much as possible. It’s an incredibly harmful thing to do (for any relationship, actually).

Yelling is never okay unless there’s imminent danger and yelling is needed to prevent it.
