why not give his entire history instead of just that which fits your narrative? he also represented slaves seeking freedom in court(for free), freed his own slaves, & hired them.
here's an excerpt from wikipedia:
"Key publicly criticized slavery's cruelties, so much that after his death a newspaper editorial stated "So actively hostile was he to the peculiar institution that he was called 'The N***** Lawyer' .... because he often volunteered to defend the downtrodden sons and daughters of Africa. Mr. Key convinced me that slavery was wrong—radically wrong."[20] In June 1842, Key attended the funeral of William Costin, a free, mixed race resident who had challenged Washington's surety bond laws."
the song was inspired and written during the war of 1812. the UK didnt end slavery until much later, so to suggest that the battles being fought were to end slavery in america is disingenuous at best. the war of 1812 had several causes, none of which had to do with Britain wanting to free US slaves. in the cases where freed slaves fought for the UK, it was merely done to benefit the UK.. not in the name of some righteous moral duty against slavery. the same way that free black americans fought for the US army, and yet were still treated as second class citizens. i wouldnt praise the US in those circumstances either... and this sadly lasted into WW2 and beyond for us.
the lines that were removed from the song, were done so because they were in reference to animosity towards brittain. and in the time that they were taken out, we were allied with brittain in the first world war. that the word slave was mentioned in those lines had nothing to do with promoting slavery and its removal from the lyrics isnt proof that it was. The UK had slaves fighting for them against the US & they were mentioned in the song, along with the rest of the enemy(britain).
very little of what you wrote is fact. almost all of it lacks context and much is left out.
Fam did you really cite Wikipedia? This isn't credible in any college/university for higher learning for any sort of Academia.
