I chose my username specifically because I did not realize how misguided I was when I was younger, but when I did see myself I resolved to learn and grow, to be constantly improving myself in some way. That includes reevaluating long-held beliefs, shedding them when they are wrong or hurtful, and apologizing to those who I may have hurt. If it weren't for forgiveness, both from others and for myself, I don't know where I'd be right now but I know it wouldn't be a better place.
All that to say, whoever hit you with that down arrow has lived either a life so pure that they've never felt the longing for forgiveness after wronging another, or a life of pitiful ignorance. Understanding and accepting Violent J's remorse does not mean we condone who he is or what he was, it means we appreciate and respect his humility.
