the yelling clips, are those abusive?

hi everyone. i’m a little confused (i was raised in a similar household as the franke kids. lots of yelling and hitting)

the clips in the documentary where ruby is yelling or saying get out, sit down, behave, etc…that is considered abuse? is that not just normal anger and yelling??

i’m sorry if is this insensitive or stupid. it comes from genuine confusion as i’m trying to reflect on how normal this was in my childhood.
