1) Don’t click on them.
Sorry, that’s all I’ve got. I had “2) don’t push the mouse button when the arrow is hovering above the link that would lead to a post you don’t want to read,” but figured that’s kind of the same thing. I also considered “3) If there is a title of a post that looks like its contents will not be something you are interested in, don’t read it,” which, again, is a little redundant.
Considering the above, I guess my title is a bit deceiving. Sorry. But that leads me to mention the entirely plausible scenario in which you find yourself erroneously reading a post you were fooled into clicking, something like, let’s say a post about Banner of Heaven. What should you do then? Stop reading. Seriously, reading histories of controversies is just too controversial. Besides, you didn’t mean to click on it anyway.
