There is normal knowledge that everybody else has/knows, and i want it also.
Is there a reason WHY I cannot have it? who determines this, and possesses the right to do so?
The “right to do so”??
What is a “right”?
That alone would answer your question.
But I am a little curious what “normal knowledge” is supposed to be. 
A right is the ability to do or have something unrestricted.
As for normal knowledge, don’t beat about the bush here.
It is common knowledge amongst Generation X/Y people that morals are subjective, and that people hold the right to do as they please. I want this knowledge also.
Oh, so by “knowledge”, you mean “opinion”.
Hmm… I don’t know that you have the right to hold that opinion (as per your definition of “rights”).
I don’t understand your points.
