We have introduced our kids to things we like and things that we want to share with them. I don't think my kids are exposed to any more than I was. I'm 32 by the way. In fact, because we don't watch tv and live simply in a remote area my kids have seen far fewer commercials than I did during my childhood. Just because I don't censor licensed characters doesn't mean I am naive. Around here it is all about regulating and compromise. Meh, this isn't a hill I want to die on. We all do what is best for our families. Just don't presume to know what my life is all about because I buy my kid Toy Story sippy cups. I'm actually kinda crunchy :P.
NellieKatz, many, if not most, MDC mamas are probably aware of sites like commercialfreechildhood -- it's a frequent topic of discussion here, and this is a pretty informed group of parents. It's possible to be aware of the counter-argument and still choose to allow the occasional Disney character into our homes. Having a difference of opinion doesn't mean that we need to be "educated" or swayed in the "right" direction, it just means that we feel differently about the topic than you do.
Regarding the general issue, I'm in the middle. We enjoy several Disney movies, and we'll buy certain things with characters on them -- mostly consumables like notepads, stickers and the like. I don't like to buy more permanent things like t-shirts or backpacks with characters on them, or with any big logo/slogan on them (as someone upthread mentioned about The Gap and Old Navy). My kids' regulation/moderation comes from me and DH.
