My daughter was telling me about a woman who runs a site with pictures of women currently suffering from or recovering from (my way of putting it) anorexia and bulemia. Apparently the lady said she had decided that these two things were not a 'lifestyle', they were an actual problem. Well, duh.
I've noticed that that word is used to excuse a lot of things. Someone doesn't have a problem, they're not doing something wrong, it's their lifestyle. Or even better, an alternative lifestyle. There, now you aren't allowed to criticize it, who are you to speak of my Lifestyle?
Got news for you. Repeatedly doing something stupid does not mean you have an alternative lifestyle; it just might mean you're stupid. As the man said, "Here's your sign".
