Feminism, Girls hating on each other ?

I was moved by this thought I had and started questioning myself , how proudly I call myself a feminist, a person who believes in equality of every gender. Yet I hold my biases against every individual specially my own gender. We never even give a second guess or hear ourselves when we girls hate each other, not literally hate but we do bitch about each other on their backs.

We say things, that no one has the right to tell women how to dress but yet we only whisper if someone wears off shoulder shirt or is wearing a kurti without duptta " the infinite haye haye's".
This sadly includes me as well I too have my share in this hypocrisy as I didn't realize this first, but now i know I cannot stand up for women's empowerment when deep down I am the only one getting envious by my own friend's work and secretly hating on her.
We unfortunately judge each other characters and sadly we have our fair share in spreading rumors about the girl who can date any guy. Today I want to apologize to every girl, every lady, every women that,  I have ever said anything about and made them feel bad, or worst made other's think bad about them and let them speak wrongly about a women, an individual I knew dearly and yet let them say whatever they wanted to and never even tried stopping it when I could have.
Let's teach our young one's, even our elder's that hate can never let anyone win and it's not necessary to have opinion on everything specially where one does not know the whole situation. Let's take baby steps towards changing our mentalities and promote positive women empowerment without any biases against any gender.
