I'm torn about this. On the one hand, my instinct for self-preservation urges me to delete. Deleting would keep my blood pressure on an even keel. I could probably say the same for my blood sugar, cholesterol, triglycerides, and thyroid hormones. Out of sight is out of mind. If I don't see their revolting diatribes, they're not sending them.
On the other other hand, my instinct for self-preservation urges me to read them. Even a quick skim through the lies and sickening illustrations may skew the results of my blood tests, but if I don't know about these things, how can I counter them? And if no one counters them, they will proliferate unchecked. If we never think about them, don't we become part of the problem?
So I read. And then I try to breathe.
