You guys are so intent on defending him, when he chose in the end to quit trying to get his family free and start a new family in England with a White woman. Here are a few things he could have done, considering the fact that he did make a decent bit of income doing speeches on the Abolitionist's circuit and what businesses/jobs he was working as a fugitive.
1. He could have saved his money and used the help of a White abolitionist he was familiar with to purchase his family with his money and a few paid to the person making the purchase. Even if none were any help, he at least tried.
2. If he was short on the money, he could have sought aid from the same White abolitionists who requested him for speaking engagements to help him acquire the money needed to purchase his family via possible charity, loans, jobs, etc.. If none were willing at this time, he at least put forward the suggestion and effort.
3. He could have done the same as (1), but instead found and paid a solicitor (English Lawyer) to aid in the purchase, since England outlawed Slavery in 1834.
He had options that he could have expended to try to get his family out of slavery, but he chose to turn his back on them and just start a new family. So yes, I consider him a c00n, because he did not attempt every possibility at his disposal to get them released from bondage. Him starting up a new family and living in relative peace compared to his original family stuck in bondage, solidifies my view that he is a c00n.
A man who can turn his back on his children in bondage and run out to start another family elsewhere, is not a man to be respected in my opinion. I personally expect him to have no peace until the family he created has freedom. Not leave them to hold their own, while he lives free and starts a new family somewhere else.
