All anyone needs to know about the ACLU is that their core commitment is to the destruction of all forms of Christianity, Christian culture, and any public Christian expression. That is all they do. That is their charter.
While they take a school to court for allowing a student to wear a 'Jesus is Love' tee shirt, they will sue the very same school for not building "prayer rooms" for Muslims and for not giving Muslims class credit for the time they miss while 'praying'. That is who and what the ACLU is.
