I am 100% in favor of public punishment without any anesthesia in these cases (rape) and I mean brutal life altering if not life ending punishment i.e. public castration (complete including testes, cut it all off). I don't care how old they are or how immature they are or if they have LD or are completely mentally incompetent... it is irrelevant - the girl will suffer with this for the rest of her life. Penises can be used as a weapon and rape is a crime of power/control - take the weapon away and the act with a penis can't happen again nor would they be able to reproduce (sterilization is a necessity IMO).
Once a rapist always a rapist, apologists will say that the 'poor boys' didn't know better or were groomed or whatever penis-pandering excuse they want to use - well IDGAF. Community service, $250 fine and the other two weren't even tried due to their age. Really? As per usual the female child in the situation will pay the price for this in her life, her community, her relationship (or lack thereof) with the child that was forced into her, and will no doubt suffer from PTSD. She is no one as the verdict clearly illustrates; she is just a girl (a female human) so no actual value in the community beyond a 'support human' role. She will never be whole, they have murdered part of her forever.
Many of you may disagree; I know my perspective is considered inhumane but these revolting aggressors have forfeited their humanity through their actions. If society keeps giving garbage humans like this a second chance we will reap what we sow.
Shit like this (leniency b/c extreme religiosity leads to lack of education and moral breakdown) is a big part of the reason I am an atheist. I'm not worried/interested about 'god's' judgment - victims should receive as close to justice as possible on earth (there is no actual justice in these cases) if they end up burning in eternal hellfire after that it is a fucking awesome bonus (but still will never make the abused whole).
Sorry not sorry.
