The person in question has many radios in the background of his videos, so maybe the comment you've replied to is into something :P

Eh, it's a stereotype. In my opinion, they should always be questioned, especially when it's an unkind one like this.

Frankly I'm surprised to see this here. Hackers have had more than their share of hurtful stereotype applied to both our hobby and our personality. We should know better. But perhaps there's a generational divide at work there.
