He has an audience, there are people there, in the room, with him, as he records his rant. As such, he is playing to his (willing and no doubt agreeing) audience.
I suppose you could conclude there are two persons present who are listening. They could easily be the producers of the video. It appears to be a listening room with records and a turntable present.
Who is he playing to: Those who have not for whatever reason given stereo, in general and vinyl particular, a chance, in so doing to trust their own perception.
For that reason I do cut him some slack, I can get that a lot of it is tongue in cheek and designed to raise a knowing laugh.
How then, is it an attack?
Now, what term would you use [An impassioned plea] (who agrees with him)
[If you agree with him you need do nothing.] To characterize his rant to start the video? Would you call it a fair and reasoned precis of the 'objectivist opinion'? Or perchance an attack, using deliberate exageration and misrepresentation.
It's his opinion with which you and others are free to accept or ignore.
You did. By the name that was deleted. By calling it a rant and strawman crap.So who then, attacked?
