A guy calls me a closed-minded educator and an idiot

I got e-mail from someone wanting me to promote something vague:

I want to share my "learning that excites, learning that sticks" absolute radical unschool program. It was 30 years in the making, but it is like no other as far as how much it is loved by students.

I have been wanting to connect with the unschooling movement, so any information you could send would be greatly appreciated.

Thank you,

I've removed the e-mail and phone number, but left the website.
At the same time he had applied to join Radical Unschooling Discussion on facebook, but one of the other moderators flicked it away without me even getting there to say "same guy, different name." He used a made-up name and had a page promoting something vague, but I hadn't known that yet.

I looked at his site and searched for more, finding one youtube video that he had uploaded but hadn't made, nor had he credited. So I responded, by e-mail:

Please don’t use the term “radical unschooling” about anything that involves the term “students.”
I looked at your site, and it does seem you only used the term because you were writing to me. I hope you’re not using it more widely.

Best wishes, if your project was 30 years in the making. I can’t find any more than the one website you sent, and a video on YouTube that you didn’t credit to the owners.

I’ve been unschooling for 25 years, and so you’re five years beyond me, somehow. Please don’t use the term for lessons for students, though.

His response:

Typical response of a closed minded educator. Only can see the negative. Unfortunate. My presentations are loved by students. Your loss.
And, I don’t need your permission to use the term “radical unschooling”! Ha! Like I need your permission? You are an idiot.

So if he's contacting other unschoolers, don't feel guilty about ignoring him.
