Question

I know a blameless and upright man, God-fearing and shunning evil.
Not especially brilliant,0
but he tries to be good.
 
The problem is that he watches Channel 14 and fills up with poisonous hatred toward the Jewish people.
He buys into all kinds of conspiracies and craziness about reality.
 
When people talk to him, he admits that on the face of it this is problematic, but there is a letter from rabbis whom he considers authoritative, who signed that it is forbidden to buy Strauss because they stopped advertising on Channel 14. So if they say that, apparently the channel is okay, or at least relatively okay.
 
How can he be brought back to the right path?
After all, his intentions and sincerity are good.
He is completely acting in error.
