Help with me & my grandma's dwindling relationship?

My grandma is almost 80 years old, not senile in the least, & pretty healthy for her age.

There’s only one problem: She’s a diehard Christian. The kind that doesn’t even go to church anymore because she thinks they’re all corrupt.

Now, I don’t have a problem with Christianity; everyone is entitled to their own beliefs. But so am I, & she’s been trying to shove it down my throat for the past 8 years.

I need a way to kindly tell her that my beliefs (mostly polytheistic, no particular religion) are different than hers. I also want to tell her that I’m pansexual, but she’s severely homophobic.

Or should I even tell her? I mean, she’s stuck to her beliefs for decades, & I don’t want to break her heart or something. Its kind of annoying when she keeps pressuring me, but should I just keep going along with it?

Help?!?!
