Reply to Arrogant DJ's VS Stupid (or not) DJ's

Good afternoon fellas, (16:26, here, Brazil)

Got pissed off this morning at a local DJ. I just can't understand what I saw earlier.

A good and decent DJ runs a DJ school. Their lessons are taught on 4 or 5 different cities across our country. I can't debate on how much he knows about electronic music and DJ. He even brought some international DJ's to teach around here.

That stated, I just can't understand why he posted a censored picture of someone asking him how could he turn one Kontrol X1 on.
The description of the photo (he edited afterwards): "Seeing that is somekind of meme posting chat windows like this, this is what is going to happen if you talk shit to me."

The updated description is "Have you tried to search on Google or read the manual? I'm not a customer service or something like that."

Anyway, why I found this EXTREMELY aggressive: It doesn't matter who you are or how famous you are, your attitudes tell everyone who you are. He is a well known teacher and I completely agree with him: it's enfuriating that some guys who ask EVERYTHING to us: "WHERE DO YOU DOWNLOAD YOUR SONGS? HOW DO YOU PLAY? HOW DO YOU MIX? WHATEVERMAN, TTYL.".

But he's neglecting this guy, he is making fun out of him, just to get a few buzz. He's being arrogant over someone's doubts. WHY DOESN'T HE RECORDED SOME TUTORIALS FOR THE X1? He could get a LOT of buzz on his videos on youtube, instead of being such a dickhead posting a picture of the conversation.

I was planning on getting a few classes on their local school on my town, but I feel that I'm going to be bullied by his fanboys.

Sorry for the rage guys.
