What helps me in such a situation, is to think back at the time, before I awakened. I defended the org, as one and only.
If something was hard to understand, I used the "wait on Jehovah" line of reasoning.
Most important though, somebody has to be ready to listen to the truth about the truth. In conversations with fellow brosis, I let them talk, without giving too much of my thoughts, if they express some concerns, I carefully try to expand them, and to help them think for themselves. But this has to be done with care and very slow.
Even if witrnesses think, that some teachngs are strange, for example the new generation teaching, or how to come to 1914 (most cant explain it anyway without help of the books) they always will remember, how the org help them to see the truth about trinity, immortal soul, hellfire. So out of a wrongly interpreted loyalty, they stick up for the org, even if they do not understand or really not agree with some stuff.
And they get constanly reminded, every meeting, twice a week, how important it is to stick to the org.
After you realize, that all this whole scheme is man-made, many things really seem weird, but what helps me, is to see the people, mostly really honestly trying to serve God. I try not to condemn them or look down on them, as i was the same just a short while ago.
Patience, esp. with your family, is most vital. Take it slow, find your pace, wait for the right moment.
