Welcome KistbyQpid!!!
I'm not a JW either. Fortunately, I found out the truth about the truth before I went to much farther. UN-fortunately, my husband still hasn't figured it out and is still pursuing it...with my kids in tow.
It is hard watching my kids be carted off to meetings every Sunday, Tues, and Thurs...knowing that their little brains are being fed. You, however, are in a situation where you are in a bit more control. I think Sirona's advice was good.
And what Ashitaka said about them feeding your mom this persecution stuff...it's all true. I had a bat with my mom about a year ago when I was "trying" to be a witness (unbaptized). She insisted on showing my kids "Rudolph the Red nosed reindeer" (the nerve of her...LOL). I got her on the phone and told her that these were my kids, my responsibility and I wasn't raising them celebrating this pagan holiday. Well, needless to say that didn't go to well. I could not see her side (and honestly, she couldn't see mine either). She saw nothing wrong with Christmas, Rudolph, etc and did not want to even pretend that she agreed with such nonsense by giving in to my (and more so, my husband's) requests that she not mention Santa around my children, or show them Christmas shows, etc. So, I stopped letting my kids go see her. The witnesses were all like feeding me the lines that Ashitaka mentioned above and using that scripture in Luke 12:49-53 and another one (that I can't locate just yet) that mentions those who give up their fam for the cause of Christ and being blessed.
Educate yourself about your mom's beliefs and how to refute them. But try, if at all possible, to avoid talking about religion altogether. I found a wealth of info at www.freeminds.org. Another good site is carm.org.
BTW, how old are your kids?
I wish you the best and welcome to the forum!
