I'm a atheist and sick of christians trying to convert me.?

I was at walmart with my granddaughter and some christians were ping out pampletsabout their church. I told the lady(bit*h)I was not interested then she asked what church I go to and I told her I was a atheist and did not believe in god so she told me I was gonna burn in hell and so was my granddaughter who is only 4yrs old and it scared her to dealth the (bit*h) was lucky i had my grandchild with me I complained to the manger but found it was his church .I'm a black witch and go with this saying A witch who can't harm, can't heal :a good witch harms none ,a better witch laughs at the good witch. if your stupid enough to be christian thats fine but why do they want to make me believe what they do?
