That's not what the article is saying. The article is not saying that Kara being offended is smart and socially conscious. The article does not judge whether being offended here is smart or stupid or whatever.

What the article is saying is that it is smart and socially conscious to be aware of the fact that Kara is likely going to be offended. It is certainly true that awareness of others' likely reactions is smart and socially conscious.

The rest of your comment is pretty much a restatement of the conclusion of the article :)
