<human>: After returning to the U.S. in 1847, Douglass started publishing his first abolitionist newspaper, the North Star, from the basement of the Memorial AME Zion Church in Rochester, New York. The North Star's motto was "Right is of no Sex - Truth is of no Color - God is the Father of us all, and we are all brethren." The AME Church and North Star vigorously opposed the mostly white American Colonization Society and its proposal to send blacks back to Africa. This and Douglass's later abolitionist newspapers were mainly funded by English supporters, who gave Douglass five hundred pounds to use as he chose. Douglass also soon split with Garrison, perhaps because the North Star competed with Garrison's National Anti-Slavery Standard and Marius Robinson's Anti-Slavery Bugle.  Douglass also came to consider Garrison too radical. Earlier Douglass had agreed with Garrison's position that the Constitution was pro-slavery, because of its compromises related to apportionment of Congressional seats, based on partial counting of slave populations with state totals; and protection of the international slave trade through 1807. Garrison had burned copies of the Constitution to express his opinion. But, Lysander Spooner published The Unconstitutionality of Slavery (1846), which explored the United States Constitution as an anti-slavery document. Douglass's change of opinion about the Constitution and his splitting from Garrison around 1847 became one of the abolitionist movement's most notable divisions. Douglass angered Garrison by saying that the Constitution could and should be used as an instrument in the fight against slavery.  In September 1848, Douglass published an open letter addressed to his former master, Thomas Auld, berating him for his conduct, and enquiring after members of his family still held by Auld. In a graphic passage, Douglass asked Auld how he would feel if Douglass had come to take away his daughter Amanda as a slave, treating her the way he and members of his family had been treated by Auld.
