I don’t think it’s frivolous to care about a celebrity’s death. I’m not ashamed to say that I grew up with his work and it’s a sad day. Now, dwelling on it and ignoring other important issues is not probably a healthy way to live, but caring about anyone’s death, especially someone whose work you admire, should not be shameful. I won’t buy into the attitude that those who care are shallow, superficial, or stupid. Anyone who really thinks this is arrogant, narrow minded, and rude.
