One of the hard parts about putting my opinion out here in a blog is that I have to turn over all my ideas and attitudes and look at them more carefully. I’ve done that, regarding computer security stuff, for around 25 years, and I like to think I’ve dislodged most of the B.S. But, when you start publishing your opinions about art, music, food, F-35s, military glory, and good scent oils to put in soap – it gets harder. Because I’ve suddenly moved into this weird grey zone where I know I’m writing about my opinion but I don’t want to take the attitude: “well this here is my opinion and if you don’t like it, F you.” Because that’s not how to have an opinion. To have an opinion you have to actually think about why you have that opinion, and then you can decide whether it’s defensible or not.
