Does Islam discriminate against women?

Why men and women don’t have the same right in Islam? they are different in many areas like inheritance ,witness , judge or adjudicate , blood money , and … while they are both human and there is no differences between them in humanity.
We believe that god is just then why he distinguish and treat them unjustly?
First we should define the justice then we would see werther he is just or unjust.
Justice means putting some thing in its proper places and give someone his deserving things or the thing which he is worthy of it , there for justice does never mean equality and being the same.
Secondly we believe that men and women are not the same rather they are different physically and bodily, if so we cant say man and woman should have the same right and equal, but there must be some differences. Because having the same right is contrary to justice.
Lets see what is the differences between them that there for they shouldn’t have the same right because its unjust.
One of the most important differences between them is different physical power and ability for doing some thing, we know the things that men can do women are not able to do specially hard works and jobs, women cant do them and if we want them to do that its cruel.
And also we know that doing these kinds of hard works need much energy and power so they should spend much while women doesn’t need these things, hence men should be paid much.
Also Islam give the responsibility of the family to man , and he should make a good and proper live for the family while woman can pay nothing even she cant milk the kids if milk can take the price from the man , and doing nothings in home like washing , cooking , cleaning and ….
There for if Islam makes some differences in their rights it is not prejudice and doesn’t mean that Islam prefer some of them I mean man or women, but the one who are more purified and believer is more valuable and worthy.
The differences are for the sake of there physical diversities and different sympathy, sensation and other things.
The creator knows better than any one else these differences, and he can say what is the mans right and what is the womens right and they shouldn’t consider equally and the same.
We as creature cant understand the exact reason of these commands and religious recepts
Because of our weakness, limitation and restriction in knowledge, power ….
These kinds of arguments and proofs are just the things that we may understand and realize by our intellect and mind.
While what is the real or factual reason we cant say any things except we can claim that these are the reasons that we can say.
