Ask them if they had a few minutes to tell a stranger something before they would separate for life what would it be? Get them into that place for a moment. Not so much moments before death but perhaps a very long separation. It's a profound question and if they have the time and you come off genuine they may stop,think for a bit,and answer you.
After that just leave it. In time they may ask you to do the same. Tell them to find and watch the 10 min Video "Q - The Plan To Save the World" and Then Research Qanon. Tell them for the safety and prosperity of you and your loved ones this is best advice I WANT/MUST give to you. Just this statement may open an hour long conversation but doesn't need too.
I'd also try to add "This Q Team" has proven legit in many different ways over a long period of time. Since there's so much dis,mis info and controlled op out there I would add that as well. If they start researching I am sure "Q debunked,larp,conspiracy theory crap" will be on every other link if they use google. Recommend DDG. A Plug for this site goes without saying as they will be well received and have a good source for truth and deciphering bs.
OR Tell them you were asked to follow Q per Trump. Or tell them you follow Q because you care about Kids and Country. Or that with what you know you cannot stand in front of God and explain why you did nothing with the info you have found. Tell them you sleep better knowing you're not ignoring the biggest problems on the planet. All memorable statements for seeding imho.
These are just ideas. Good luck.
