I have a cousin and a BIL on exact opposite sides of just about every major issue of the day, to the point where some of their postings are of the raving, name-calling, tinfoil-hat-wearing variety, so I'm getting hammered from both sides ("Tastes great!" "Less filling!") It's taken me about 2 years to learn to just scroll past the nutty posts to the ones I'm interested in.
I have to keepreminding myself of the cartoon caption: "I must take action! Someone on the Internet is wrong!!!", because really, it doesn't matter. I'm not going to change their minds by pointing out any half-truths/untruths/myths they post; I'm not going to inform or enlighten them or the people who agree with them, so why bother? Take a deep breath and move on.
I just wanted to laugh at your reference there in the bold. That's all.
(Oh, and the "Someone on the Internet is wrong!")
I wish you could set Facebook to filter out all statuses with trigger words like "Obama" and "Limbaugh" and "conservatives" and "liberals" and "Pelosi" and "Rand" and "guns."
I suspect that if you use "Only Important," then you get posts that have a lot of likes/comments. If I'm right, then that may not help in every situation, because those rantings may get a lot of likes, etc.
