If someone disagrees with you on what is and what is not a threat to someone (anyone), wouldn't you want to debate them to hopefully change their mind so they see the threat and can take proper action?
There is a diverse set of peoples in this country with diverse problems. So it's not just what hits home for you that you'd want to warn people about and inevitably start a debate over, it's that you care for people who have nothing to do with you that you'd want to warn about danger.
And when you warn people about danger they face, they may disagree with you and when they do, a debate starts. Sometimes debating goes hand in hand with caring.
