I'm going to force my brother to follow an established system
What kind of system are you wanting him to follow?
It's called the family coercion system. It involves extended periods of silences.
I believe it's important to have a set of rules for the family, but you shouldn't force anyone to do anything. I think it would be valuable to explain your family why this is a good system.
I know what's better for my brother so it's not necessary to explain anything.
I understand you think that you are in the right. But simply communicating why you think this is good for them is going to help out the whole family. I assure you this would make for a positive outcome.
