I'd like to congratulate you on your courage on trying to awaken your mother, the ever present we are in a faith that is true and pure mind set that is implemented into the witnesses
and that all other religions are corrupt and evil. The fact is they are like the others and have the same problem and that is wolfs corralling with the so called sheep looking for prey.
The JWS brought this on themselves with their two witness policy for acts like this, like pedophiles go looking for an audience before the attack, really.
Your mothers response was what you would expect from someone who is fully indoctrinated, you shouldn't be all too surprised by that, but at least you offered
her something to mull over for a few days so it was certainly worth it from my viewpoint.
Keep chipping at the tower and tower will soon collapse, but be patient and compassionate in your approach ......good luck
