I belongs to Hindu religion but I want to change my religion to buddhist.?

I want to change my religion just because of the castism in Hindu religion. I belongs to a backward cast. And i found so many hurdles in my route due to this castism system.. Hindu people are still stick to the castism and dont want to forget all these useless things.. Not only me but lots of my brothers and sisters are struggling in this democratic country due to this castism.. We are just saying that we are living in this democratic country but still we dont get any freedom in this country.. every where we struggle due to the cast.. I belongs to a very well educated family and just because of this castism we are facing so many problems.. Even we are not able to tell any where our cast if somebody asks.. We are also human beings and have a right to live like all others are living but the system doesnt allow us to live like others.. As Dr. Babasaheb Ambedkar says " I dont want to die as a Hindu " I also want to say the same thing As I take birth in a hindu family but dont want to die as a Hindu..
