I'm going to tell my family how selfish they are.
Why are you gonna tell your family that?
Every member of my family is left wing and they only care about social issues
It's good you want to bring attention to the issue, but your family's political leaning doesn't mean they're selfish.
It does to me, so I'm going to let them know how selfish they are.
You shouldn't let politics interfere in your family relationships, it never turns out good.
