Yes, I believe it is a good message to spread because the way women were treated in the early ages was unforgettable and we need to make up for that. Although some people may think it is sexist I do not. There can be man power if you want. WOMEN ARE STRONG.
First off "Girl Power" sends the wrong message. You are dividing children, at a very young age, by their gender. It might start a sort of "ultra nationalism" but with genders where girls think they are smarter and overall better than boys because, well, a TV show told them so. This is sexism and ultra ironic, you try preaching anti-sexism when it causes sexism. This mode of which girls think they are better can cause serious psychological issues in their lives. They might begin thinking that just because they are white, they are better than anyone else. They will discriminate guys all around, and think the root of all evil is not money but males. They might not affiliate themselves with guys early on thus making further encounters more awkward.
Girl Power to me does not mean sexism or that girls are better then boys. Girls were pushed down and did not have the same rights as men, this effected their self-esteem. Girls needed that boost to be assured that they were boys equals and now we have that assurance. This has nothing to do with the race of girls but that well-needed equal boost that we got.
You say that girls were pushed down. That would be true, if this wasn't the 21st century. You acting as if an 10 year old girl has goon through deep seated sexism that was present in the past. Society has changed from it's past sexist ways. Instead of trying to divide children by their gender early on, why don't we preach equality and co-operation? This would show kids that male and female are one in the same and should be treated equally. It also aids co-operation between the sexes and will diminish sexism. This will also translate nicely in other aspects of their lives. They will realize that everyone is equal and will translate the theme of co-operation between sexes to things like nationality, race, religion permitting a more peaceful and aiding society. But using your division method, it would promote an unhealthy competition between the sexes (and other aspects later on) and diminish co-operation and equality.
Stories, Novels, and Newspaper clippings can still show modern day girl the grief girls were put through in the early days. Males and Females are now equal... because girls have learned about the true meaning of girl power. Without girl power many girls self-esteem would be low, feelings would be forgotten and no girl power would mean no equal jobs for men and women.
You just said that Males and Females are now equal, then why do we need this now? Sure, we might of needed girl power back then but now, we are equal just as you said. If we continue pushing this girl power then of course we will reach a point of non equilibrium were girls while become self-entitled brats and think they are better than men. Also, I don't know why you are pushing just girl power, when around the board, teenagers have depression, low self-esteem and even commit suicide (both of the genders). Instead of girl power, I purpose Teen Power, to show teens that good looks aren't everything. This hits 2 birds with 1 stone, you help male and female teens and improve the co-operation between them and understanding of the difference sex.
Thank you pro for starting this debate.
