Opposition The ACLU et al are not sources on the Constitutionality of this Act  They are protesters  SCOTUS is who decides Constitutionality and as they havent ruled one way or the other there is no source on Constitutionality So if you wish to keep this section labelled Constitutionality then  you must use relevant sources  which the ACLU and Maldef and others are not If on the other hand you want to relabel this section to Opposition then the ACLU et al are relevant Im a pretty flexible editor  You can decide which direction you want to go  relabel the section or remove links to sources which arent sources on Constitutionality
