I don't generally revel in the misfortune of others, even when they bring said misfortune upon themselves with their own stupidity. In the case of racist douche bags though, it really is satisfying to see them pay, in real terms for their ignorance. Losing his positions with HOA and his job forces him to deal with his actions.
Sadly I'd guess that rather than learn from this, it will just make him double-down on his racism. Obviously I don't know this for a fact, but I'd guess he would be likelier to blame everyone else for getting him fired, rather than looking internally and realizing his own mistakes.
