It's definitely NOT you. Even though the majority of your family is misguided, they really only have the best of intentions. But you know what they say about where good intentions can lead you...

Good for you for getting out of there and living your life on your terms. I would imagine that their judgements towards your orientation, career goal and job are all incredibly invalidating. Just as others have mentioned, gently remind them that these are your choices and that you are happy. If they still argue with you after that, then just ignore them. If they love you, your happiness should matter. Simple as that.
