Some do, some don't. I'd wager there is a good number of both. I'd also wager those who don't care form a larger group, but that those who do care form a noisier and more adamant group.
If those that do are interested in organizing a boycott, and if they can make a big enough stink to be effective (somewhat doubtful), then they're welcome to do that.
If not, they can at least watch out for their own.
For me, I don't think what toys kids play with is so very important, but I think the issue is interesting as a symptom of various other things - inept parenting, change in standards for women, etc.
The only significant trend I see in marketing for kids is the "urban" trend. Apparently there's not much to do in the 'burbs and the city looks like fun to a lot of kids.
