Definitely generational influence. My parents, born in the 50s, also made sure there was no pink on any meat or else it was considered "raw".
My mom does have some great meals that I love to enjoy when I visit. Unfortunately, she still thinks that her roast beef dinner is one of those highlights. Entire thing is a weird greyish color all the way through. As kids, we would just drown it in A1 or whatever. She still thinks this is normal and I honestly do not have the heart to tell her I can't stand it anymore! Pretty sure my sister cooks the same way. Just me and my brother have modern meat cooking mindsets.
