Perhaps your mother is fearful due to her own experiences. In that position I would quite frankly let my Mom know that what is for me is for me and that she has no business trying to prevent me learning about life. I would compare my struggle as a Jedi to her struggle as a lesbian, neither are broadly socialy accepted, lesbianism is moreso now thanks to gay rights activists and social equality programs, but she should be able to understand that you are who and what you are and that she can either accept it or not but it will not change your steadfast life path. If she tries the old “not in my house” bit, simply remind her that merely by imposing ridiculous restrictions on your life she is creating division between you. Explain that you want to be able to have an open, honest and loving relationship with her but that if she continues trying to restrict you that it can only lead to deception on both your parts. You being who you are, yet masked from your Mom and her using fear and danger as a manipulative tactic to further her own apprehensions about life through you. Ultimately it is your path to walk but I’m sure you’d both be happier with one another in acceptance of each other.
