the best way ive found to approach this, is the flip flops on transplants being cannabalism and fractions as they involve lives, how transplants were ok, then cannabalism, then they changed their mind and they were ok again, then show the scripture about people changing with every wind of teaching because they arent spiritually mature and they havent trained their conciences, then demonstrating how we go by the conscience and whims of others, Jehovah never changes, but the opinions ofmen do.
Relate that to how we point out how science changes its mind, and say was it humans or Jehovah that was responsible for those deaths, cognitive dissonance will set in, but Jehovah usually will win.
Then another subject witnesses dont accept is everyone will die at armageddon but if you died a year before your good, point out how you know worldly people who think theyre christian and doing good serving God, and theyre better people than (yourself or something) but they will die just because they were alive at the wrong time (perhaps point out one of her family members)
The thing is force always meets with force, if i were you, i would say they didnt lie to be mean, or back off from that entirely, point out they lied later on because they wanted to protect you, however thats becasue they dont trust in your conscience or Jehovah, give the example of an overprotective parent.
But some lies were how they present 1914 and such, that however at this point will get you nowhere, you can demonstrate dishonesty and not quite lies, the quotes out of context are another thing, one of the most damning dishonest things, is how they were all "get ready for armageddon" and then " "some" thought armageddon was coming but they were immature" that was BS but those are old watchtowers which you would have to buy and show , and thats not going to work at this point anyway, if you have to have to article and cant shoq internet quotes, they arent ready anyways.
