As a SM that's just a shy, quiet, normal person that just happens to love a man who has previously procreated, I've particularly struggled with the stereotypes that were generated the instant I married a man with kids. Because I don't feel like I changed at all from being single to being married. I'm not suddenly evil, or overbearing, or overstepping, etc.
So, for the past couple of weeks or so I've noticed that SD9 has been referring to me as "my dad's wife" instead of "step mom" when talking to other people. So tonight I asked her, just out of curiosity, why it all of a sudden changed from "my step mom" to "my dad's wife". And she said, "Because I feel like once I say step mom, people will automatically assume you're mean, and I don't want them to think that".
It was an interesting illustration of how deep the evil SM scenario goes. Anyone else have any experience with fighting these stereotypes?
