As much as it pains me to say it, yes they do, particularly my mom (who, I must point out, I love very dearly and am very close to). My mom tells me that now that I'm an adult, I should do whatever I want to and that she doesn't want to hinder any goals I might have. She even periodically asks me out of the blue if I feel like she's getting in the way of my goals. But whenever I tell her that I want to get a job, she says that I can't either because I'm on Social Security, or because I wouldn't be able to handle having a job emotionally. And whenever I say that I want to live independently (or at least in an assisted living facility), she becomes very upset because she doesn't want me to leave. She also gets very defensive towards other family members or friends who suggest that I take steps to become more independent. She'll flat-out admit that she's way too overprotective, but she doesn't care.
On a similar note, when I first came out as bisexual and told my mom that I felt androgynous rather than 100% female, she was very understanding. She told me that lots of celebrities, such as Angelina Jolie, are bi. She even told me that she didn't feel 100% female either, that she just feels like a "person" rather than feminine or masculine. But over the years it seems that she has changed her mind, because she reacts with disgust whenever there are references to lesbianism on TV. And one time at a thrift store, I wanted to buy a shirt because of the design on it, but my mom made me put it back because it was "a man's shirt" and she "[didn't] want [me] wearing men's clothes."
