<human>: Provide a brief overview of the text.

I thought they were going to kick me out, but I still live with my dad, and they all still love me like hell. The only thing is, whenever we talk, they ask me why I became an atheist, but they counter whatever reasons I give with "well the Bible gives me hope" or "evolution's just a theory" or "science is fueled by liberal politics." My dad thinks I might be gay (I do a pretty accurate impression of the stereotypical gay guy) and that I just became an atheist so that I don't have to deal with the conflict of being a gay Christian. My grandparents think it's either some form of rebellion or it's because I was hurt somehow earlier in life and it's a coping mechanism. How do I defend the validity of my lack of belief while maintaining a good relationship with them?
<bot>: my family still loves me and doesn't mind discussing my atheism, but they dance around the topic with fallacies. How do I maintain a good relationship and defend myself too?
