How to treat offensive words

It's an offensive picture. It should be. It's an offensive word. But some context here is important. This is a stretch of beach near my home that's lately been made inaccessible by both a higher tide and the loss of some boulders people used to get around the fence the owners of this stretch put up. It is also close to the water so it can only be seen if you approach it from the lake. Finally, it seems to have been scratched into the face of one rock using another.

I remember as a young tween being overwhelmed by the power of some words to elicit responses from other people, not always responses I liked, and sometimes totally out of proportion (to me) to the relative smallness of the word or the intent behind it. (In a related way, this is also about the time I began to understand how written or spoken words could have an effect on others, which opened a whole new way of being to me.) I had a litany of words I thought were offensive that I'd mutter under my breath when I was angry or frustrated, including the above word and, for some reason, "booger."

So my suspicion is the above, hidden away as it is, and using a tool that was at hand rather than brought along like a spray can or even a marker, is the result of a young boy (it's almost always boys who write these things) just feeling the immensity of that power, the way a simple (so it may seem to him) word can make some people angry or giggle or turn serious or agreeably nod. For his purpose the word could have as easily been "cunt" or "faggot", words that aren't likely to come up in normal conversation and have no purpose except degradation and insult.

When I was a grad student I wrote a bunch of phrases in chalk on the walls and windowsills of my office, like "Stop praising dust!" and "Fight the power!". I was gratified, visiting a friend a decade later now in the office, to find that the phrases, or what was left of them just above the height of someone with an eraser, remained. This is not, of course, exculpatory but it is suggestive that the proper response is not to react against it (unless you happen to know the person who did it) but to let the rain and waves handle it.
