The rights that are guaranteed by the Bill of Rights that cannot be taken away are classified as civil liberties. Many people get civil liberties and civil rights confused, although they are different.
Civil liberties are more grouped as the "basic freedoms of the people". The Bill of Rights, which are the first 10 Amendments to the United States Constitution, guarantees both freedom and equality without discrimination. Civil liberties can never be taken away, not even by the government, as they are yours to own forever. Things like freedom of speech and religion are things that cannot be taken away, this helps the government stay in its place without interfering too much with our lives and abusing their power.
Civil rights are similar, and as I stated before, are also in the Bill of Rights, but have to do with discrimination. Your freedom should not be taken away due to discriminatory purposes such as, race, gender, or religion. You shall have the freedom to do everything anybody else can do.
