my work is transformative in nature as a criticism so some usage of the original is required but uses no more of the original than is necessary & this has no negative affect on the market for the original work its self & my work is protected speech as outlined by the 1st amendment to the united states constitution & falls under fair use as outlined in united states copyright laws
