ban on commercial stereotypes

What do you all think about the ban that is being placed in the U.K. It won't be in affect until later this year and will most likely effect what we see in America. They are planning on banning stereotypical commercials that protray gender roles. Such as a little girl being a ballerina while her brother studies science. I fully support this and I believe it will reallly show kids that they can be whatever they want in life. People against it are saying that it goes against their freedom of speech. What do y'all think ???
