My thoughts are similar to Shadowgod's on this one. Seeing a little hope, or having positive messages can empower people, especially young ones, and let them know they're not freaks.
Being on line got me to "witness" some drama, as a talented kid (the one whose art I posted in the laughter thread) first let me know of having found a BF, then got pulled off line by his parents when he came out. It seems some Marvel comic had given him the courage to do so, and he thought that it would turn out just as in the story... Hence a fun-loving, gifted kid is likely to grow bitter, thanks to bigoted parents.
So, no, life is not all pink and easy. At the same time, all the information this bot got, and the (hopefully) thoughtful words we exchanged may also help him to get through without being brainwashed.
And with positive stories and testimonies, you have to think about long-term consequences, when it will eventually become a non-issue.
So yes, we don't have to ignore the problems and discrimination; let's try to voice out a positive message, and then fight for what's right. These go pretty well together.
