They kind of are. I mean, for most other jobs, you're right--your emotions are your own responsibility. But advertising (inasmuch as it's more than simply "getting the word out") is all about harnessing peoples' irrationalities in profitable ways. And that means avoiding triggering irrationalities and biases people have that might scare them away from buying what you're selling.

For example, the last thing you want to show in a computer ad is a picture of the machine with an IDE open. Because IDEs are intimidating to a lot of people, reminding them of skills they lack ("I'm not good with computers.") And "intimidated" is not a buying mood.

(Also, as an aside, I'm not sure in which sense you meant "you," but to be sure, I wasn't the poster you first replied to.)

Framing this as a "responsibility" is the wrong way to look at it. If an advertisement makes a significant number of people feel negative emotions, it won't be effective, and what good is ineffective advertising? Who cares who's right, wrong, good, or bad? Much less who is responsible?

I'm a flawed person. I openly accept that. I don't think my emotions in this situation are unique though, and I don't think they're basis to refer to someone as incorrectly functioning. It's what we do with those emotions that make us "correctly functioning" or not.
