So one day, when I had a couple of hours free I sat down and read every single link. All of them.
The lack of substance beyond an opening paragraph that claimed a point was appalling. When it was brought to the attention of those link-bombers, they actually agreed that there was no substance and that they hadn't read those links at all. I was really proud of my friend and thought we had actually resolved a political disagreement on Facebook.
Then I saw them dropping the exact same links in another conversation within a couple of days.
Facts without context don't prove anything. Some of the facts but not all of them just frame the story in a particular light.
After years of this stuff, it becomes clear that nobody has time to become an expert on every subject just to be able to identify the critical details that people are leaving out.
Eventually, you just research your positions on the subjects that matter to you and vote accordingly. Now, if something doesn't make logical or mathematical sense, I oppose it. If there's no logic or math involved, I generally take no position at all.
