Opinions Not Based on Fact

I'm frustrated to see so many people take on the opinions of others with no verification or validation of facts! Just because someone "says" this or that, they believe it, even if it makes no logical sense. Quick to judge and find shortcomings yet offer no solutions for the problem attempting to be solved.

How do you have a conversation with some who does this? I've found I just move on and away, seeing that any attempts to discuss information based on research and readings will still be disregarded.

Meanwhile, I'll continue to be open to new information, new research, new facts on which to base my opinions.
