Yes on relationships.
I'm not trying to compare specifically to politics or commerce. What I was getting at is that all relationships between individuals (romantic, familial, etc) are based on communication and therefore evoke the same kind of ethical considerations. Consider:
How responsible is a father / daughter / lover for the sensation their words evoke?
By shifting to this meta level the implications of privileging intent over consequences, the emitter over the receiver, etc... might be more apparent.
So for example, my fundamental principle is of free will. And therefore I will typically assume the receiver is much more responsible for their reactions than the emitter. At least when it comes to words, expression, and most art ;)
I don't think this removes any accountabilty from the emitter, but it relativizes it.
Also, I think I am in agreement with your comment regarding romanticism (I'd say rather postmodernism) in a broader sociological perspective. But I am not an expert on art history and not sure the aesthetic is what you're querying. So to clarify, are you saying the recent (well, relatively speaking) trend towards subjectivy expressivity, abstraction, pop art (in any combination you prefer) is:
A - harmful
or
B - disgusting
or maybe both?
