I'm going to point out how dysfunctional my family is during a visit
Why would you want to make your family uncomfortable.
I want to make my family feel ashamed of themselves. I can't stand them.
You shouldn't say bad things about your family. You shouldn't call them out and make the feel bad.
I don't care, my family is fucked up.
Even if you think that, it's mean to insult family members. Why not just try to get along with them instead?
