There's nothing disrespectful about not wanting religion stuffed down your throat. But you're 16 so I'm going to put on my mom hat here. You're likely being simply viewed as a petulant child in the situation you described, rather than a "disrespectful atheist". If you had said "no, not wasting my time" to anything else that had nothing to do with religion, the end reaction from your family would likely be the same - "petulant child", which has little to do with religious beliefs or lack thereof.
