Having the right to do something for yourself is not the same thing as having the means to do it. You and I have the same right to free speech that Rupert Murdoch has, but we do not have his media empire. Still, that does not in any way undermine the value of the right itself. As long as we have the right we can try to do something about getting our message across, but where there is censorship, no amount of newsprint will get over that. Second, a right must apply to everyone.
Freedom of speech is only a right if everybody has it.
Rights, unlike privileges, are universal. We often talk about rights for women or for black people, but the reason those claims have any meaning is because we are demanding equality of rights, not special treatment. Black people are denied equal treatment by the immigration services, and singled out for special attention by the police. When we say 'rights for black people' it carries the force of a demand for equality. The confusion about rights arises when other kinds of claims, get called rights, claims that are not rights at all, just entitlements or even privileges.
