Human, for myself when I first started stumbling acorss these things I was just total innocence "Oh my god, look what I found, can you believe this" and I meant it.
I had to push these questions on everyone in my life, my parents, siblings, even my ex because at that time we still had strained contact.
I didn;t question how I should go about presenting it to them, I simply did it, if they asked me how I found it I always said I was looking up some hadiths for learning, or reading the quran online, or looking for stuff to strengthen my faith and stumbled across this.
It is true that they eventually asked me to stop showing them because it was messing with their faith too, but I was quite angry, I needed to share, so my advice just share, just be shocked, just show them, bring it up.
What can they say? it's not like you are doing anything wrong, you are simply trying to stay faithful and need help.
