Explain to me why this topic is so popular?

It's fun playing with FE people. Why? They are intelligent enough to cleverly use pseudoscience in ways that are puzzles. They are probably not trolls in the standard sense of the word, but they twist the things of science to interchange them with pseudoscience in intriguing ways.
Everybody likes a puzzle. Everybody likes a riddle. Some people give up with difficult puzzles and riddles. Others, who can see the answer, but aren't able to explain, might get angry.
That's all that is happening here. The FE people have made a riddle for anybody. And they are good at "trolling" the words they use to maintain the riddle... somewhat.
