Then don't use them? As a reader, I certainly appreciate when people do. When writing documents or HTML I use them because it adds clarity. When typing on a web form, I'll usually use "--" because it's visually similar and much easier to type on a US keyboard. No one, pedants included, have ever tried to correct me on it.

I also use capitalization and punctuation when I type while many people do not. It'd be great if they did, since it makes reading easier and takes almost no additional effort, but I'm not going to let it ruin my day. The parent comment is about why the distinction in dashes matters and has virtually nothing to do with typography enthusiasm, but rather reader comprehension. If you don't want to integrate that information into your life, great, but that's not really a refutation. For my part, I found it interesting. Even though I use em-dashes I learned more about how they're helpful. If you don't want to use them, I'm almost positive no one is ever going to correct you.
