Lighten up.
Actually it is you who needs to lighten up.
You post 'Sheesh, who cares' on a thread that obviously many people do care something about, the murder of an innocent little girl.
Rather than being adult about it and going on to the next post (sort of like turning the channel when you do not like the show) you just needed to make a comment like that, which was obviously directed at those who are interested.
Your post implied that the people showing interest in this subject must be nuts, fools to even care because the great California Patriot sees no interest in the subject.
You have every right to enter posts that are obviously intended to belittle those that are posting. Do not act so surprised when you get a negative reaction.
Grow up and have a nice day.
