Hi searchfortruth
Can you tell your wife or elders that you got these informations that made you start to doubt on Wikipedia? On Wikipedia are also a lot of critical information concerning WT and Wikipedia is not considered an apostate site.
Only if you can't hide it anymore tell your wife that you found some information on jwfacts that is troubling you about xxx (maybe you know a matter which your wife has doubts too).
When you talk to elders or your wife, try to use questions like. "Honey, I just don't get it why we have to refuse white blood cells because a baby drinks a lot of them in mother's milk.
By the way. Human Rights Art. 19 says:
Everyone has the right to freedom of opinion and expression, this right includes freedom to hold opinions without interference, and to seek, receive and impart information and ideas through any media and regardless of frontiers.
