Aaah....we can't please everyone, even if they are the people we love and who's opinion we hold close to our hearts.
Ultimately, you sound like you are passionate about what you do (work) and proud of it. Go girl.
We can still value and hold dear to us our relationships with the people we care about and maintain our own 'place' in life. We can't expect our parents to agree with everything we do or have a passion about, but we love them no less.
If we spend the rest of our lives constantly worried about what other people think or how they don't 'get' (understand fully) what we do, we will never trully be living our own lives to the best degree.
We are all individuals, with our own perceptions, feelings, values, beliefs and so on. And need to respect and acknowledge the same of others.
As for being a 'radical' - yep, I'm one too. I've always thought laterally about life and 'looked-outside-the-square' and have tried to always maintain a healthy sense of who I am and what I uniquely believe in. I can't be someone else, I am me.
Your parents are proud of who you are, from what you say. There are alot of people in this world, who, sadly, are unable to tell us they receive the same adoration from their parents.
Agree to disagree and enjoy your life.
Wish you well.
