To be fair, seen from outside, this seems something strange and, in my opinion, not good about the American culture: there is always somebody to blame for your problem, a reason why you are acting in a given way, an external cause if you suffer a medical problem, eat too much, put all the kind of pills in your body, and so forth.
Probably this is representative only of a minority, but from the outside this looks like a vocal minority, and even a very small minority, if can feel offended, or addicted, or something else because of your work, can easily turn your work into a nightmare.
Now the thing is: it is not true. You, with your work, are not forcing anyone. We live in a world full of possibilities, the problem here is, to be able to critically analyze what you do, otherwise there is no thing that can save you, you'll misuse even the simpler things to cause yourself some kind of problems.
There is more, even controversial things have some very good impact on the life of people making judicious use of those things. Example: a violent game can be a way to express violence of an otherwise repressed person, or some other people that is having a few bad weeks, is finding an escape playing at it. Similarly alcool, that if abused can be bad, addicting, and destroy people, is the joy of many people having a glass of wine from time to time, and so forth.
Most of the times the problem is not the tool but the user.
