To be honest, I couldn't care less what they think.
My mom: Fears I might get addicted, and thinks that studying is a priority. But generally she's convinced that I'm a good player and doesn't oppose to it (anymore).
My dad: surprised that I made so much money out of it already, but thinks it's great.
Let's not mention my 3k loss over the last 3 weeks ♦
I casually dropped that if I were able to live from it, I would, and I at least didn't receive a negative reaction. I think they realize that no matter what they say, I'm doing it anyway (as I always do ;)), so they stop bothering to lecture me and just let me go my way 
My friends, who are mostly poker players themselves, are a little bit divided: some think it's great, some don't understand and still see it as "gambling", no matter how many times I explain the concepts (BRM, TA-game).
