Debates are for the Lazy

When Dr. Heiser said "debates are for the lazy," he didn't necessarily mean that they're lazy for the debaters who are doing the debating, but he was talking about those who intend to use debates as a substitute for real study and research.
//Debates are for the lazy. What I mean by that is that, if someone really wants to learn something, they’ll study and do research. They won’t be content to be entertained. Debates are a substitute for study. They are academic bloodsport — entertainment for both sides that allows both sides to avoid the hard work of studying.//
Do your own work; this means that you need to engage every side with fairness and clarity, using a good faith approach that doesn't run out the gate with the idea that you're just going to defeat one side before you've even looked at it properly.
That being said, there are many times when ideas can be discounted basically out of hand if they have no evidence, no logic, etc. Don't waste your time on nutball ideas.
If someone wants their idea to be considered in the realm of sensibility, they do have a responsibility to present it in a way that affords a reason for a critical thinker to spend their valuable and limited time looking at it. We should insist upon that evidence rather than spend our time chasing fancies.
"Oh but it's fun looking at all these ideas."
Then call it what it is: entertainment. Fiction. Storytime.
