Exactly, it goes both ways, especially if you make an insensitive joke, be ready for the back lash as is right, not everyone finds your humor funny and they shouldn't and we can take offense and we don't need to tolerate such speech, and you should BOO, and jeer, and heckle to your heart's content, as freedom of speech dictates. It's got nothing to do with healing trauma but everything to do with ones values, usually "trauma" is not something people step into attention because, but in spite of, and rightly so since nobody wants to readily and willing relive trauma simply to make a stand on moral grounds, outside the righteous masochists.
