Salaamun Alaykum
I'm sorry to hear of your situation. I (as well as many others) have gone similar experiences. The best thing you can do is remain on good terms with your parents, and slowly make Hijra (migration) to Allah and His Messenger [sawa]. You are under no obligation to share with them your feelings about this at this present time. Especially if you fear a negative reaction may follow.
You can simply tell her that perhaps Islam is perceived to be a "male-dominated" religon due to the ill-treatment of women by some men. Sadly, this is a human problem, not something isolated in the Muslim community. You can respond by stating the status of women (e.g., that the Prophet said in a famous hadith that Paradise lies under the feet of mothers) that you have found in your research of Islam.
I have not read it, but have heard from others that this is a nice book to consult on this matter: http://www.iranchamber.com/personalities/mmotahari/works/woman_rights_islam.pdf - it is by Ayatollah Mutahari.
Keep on reading, here and there, and you will learn and grown with time, effort, and patience.
As a side note, I'm certain you will find this fascinating and beneficial:
There exists in our faith a notion called Taqiyyah whereby one can conceal their faith for the presevation of life, amongst other things. If you were to become a Muslim in the near future, it is perfectly fine if you keep it to yourself. Allah is aware of your struggle and effort and knows He is your goal and desire. He will make it easy for you, insha'Allah.
If you acknowledge Allah and the Prophet [sawa], the next step is to act on that knowlegde and on whats deep in your heart. This is done by affirming God's Oneness and Muhammad's [sawa] truthfulness by saying the Shahadah and entering completely into Islam. You do not need anyone to be there to 'confirm' this. It is between you and your Lord. I understand perfectly if you feel you are not 'ready'. It is a strange state to be in and one I recall very well and was lingering in for far too long before I felt I could no longer sit on the sideline - so to speak - but I had no other choice but to plunge into the ocean of Islam. Under it's surface, I saw, and still do, see nothing by Light. It is no exaggeration that I wouldn't be where I am now if it wasnt for my decision to accept Islam, the Prophet [sawa] and his Family [as].
You will know when you are ready, your Lord will call and your heart will respond.
At the end of the day, no one is better at discerning what is appropriate in your situation more than yourself. Be sincere in your supplications and prayers to God and always rely on Him. We are here to help as much as we can, insha'Allah.
If you have anymore questions, please do not hesitate to ask, or inform us of your progress.
