you've done your duty/job simply by sharing the information
if your neighbors get sick and die because they failed to heed your friendly advice, that's on them
it's more likely than not that in time, they will recognize that you were pointing them in the right direction
I was on friendly speaking terms with a co-worker for years, and he hasn't spoken to me in two weeks because I shared with him some of the scientific papers on HCQ (with no derision towards libs or other editorializing on my part).
Maybe one day he will come around too.
