Talking with someone at length, I came to see that I actually have no responsibility whatsoever to change anybody’s mind!
I have no responsibility, or burden, to even change the world. ‘I’ cannot do it anyway. This is remarkably freeing.
What I can do is the very best, which is existing in the most harmonious and felicitous manner possible given the world is as it is and people as they are (which entails deep flaws and utter horrors and unbelievable madness) – and present facts and opinions to people as it may happen, and thereby give anyone I come in contact with the best chance they can have to perk up and take in what is being presented if it interests them.
And there’s really nothing else other than that! No responsibility whatsoever, how very freeing 
This also means, of course, that ‘I’ do not need to be in control for this…
