Why does everything on FB need to be confronted with the negative waves?

This may appear somewhat contradictory , but I'm going to throw this up anyway. Just about every time I take a gander at my FB newsfeed, somebody puts something up that they are proud of, and then there is a ton or two of people that jump on and say how bad, or stupid, or wrong, or just find fault. Just like last night, I saw where this guy had just got his wings. Instead of most saying congrats, no ten people had to find fault. Is everyone so damn pissed at the world, especially their own lives that every good thing is ridiculed ? Where every good thing has to be knocked down, and somebody has to be mean and bad mouth something, instead of someone just perking up and saying hey good job? 
Just about every damn day, I watch the news here, and see where some cop somewhere in America is getting shot. Now I know that every cop isn't perfect, they have bad days, but I'd easily put myself in harms way to protect an officer rather than see one get shot. The person who puts on a badge, has to face things you'd rather not even think of. Show a bit of restraint on your part, you'll get a better outcome with that citation the officer is about to write you. I'm getting off course. Are you so mad at America that you need to shoot those who protect you? Sure I bitch a bunch about Etown Wyoming here, my intention is not to demean the town, its more to give it a kick in the butt and say do this, and stuff will get better. I am very lucky and extremely blessed. Every evening after it cools off a bit, I go out on my patio, and watch the birds and the moose family just beyond a plastic fence. The peace of the breeze and the slight movement of the clouds, and I think, just as in the song, My what a wonderful world. Sometimes you have to die a little to learn to live, to take a bit to be able to give. Even fail to appreciate success, what you don't need is people in a public forum, bitching at someone that just did something and achieved something. Be nice and cool remember the Commandment? Do unto others as you would have them do unto you. Plus all this of this Lives Matters junk, all lives and souls matter. It don't matter if your black, white, yellow or blue, Everybody matters, both to us on Earth and to our Heavenly Father. Maybe its time you turned off your Facebook, newsfeed and read your bible.
