**Perhaps they’re just not interested.**
Oh, they are interested. You can bet they are watching every FLDS thread, just as I often read threads without posting on them.
Not necessarily. Some people do have other interests and other demands on their time.
At any rate it would be foolish to presume that because certain LDS posters are not commenting on FLDS threads, then they are de facto supporters of the polygamists.
Some might be, but you don’t really know if they do not say as much.
