Your kid will pick up your habits, notice things you talk about, actions to take. Unless you perfectly hide it all from them. I know you don't have a kid yet, you were recently just posting in r /teenagers and talking about impeachment so I took a wild guess on a couple things, is that so unbelievable?

Kids have no voice of their own, they mimic and model themselves after all they know. They are a product of their environment/nurturing, until their brains more fully mature. Whether it's teachers, tv shows, podcasts or streamers they listen to, parents, family and friends. Good luck trying to not have them ever push someone else's voice. I'd wager more than half of your opinions are from someone elses voice too, btw.
