"You are not the jackass whisperer."
"Don't try to win over the haters. You are not the jackass whisperer." - Scott Stratten
There are too many people out there who will appreciate you, your ideas, and your opinions. Feeding into negativity is like feeding anything else. It will only continue to grow.
People will continue to hijack LinkedIn posts to be negative and create hostile spaces for arguments. There is a way to share your disagreements and debate respectfully.
If they can't do that, say thank you and keep it moving.
