First, one piece of opinion in a larger body of text doesn't tell you "all you need to know" about the rest of it. Much of the other arguments might be very good even if a few are wrong. What a silly notion to say otherwise.
Secondly, whether Falun Gong was cult-like or not doesn't change the fact that China brutally repressed a religious movement of tens of millions of members that didn't engage in terrorism, violence or forcibly integrate new members. This repression coupled with so many of China's other repressions of different groups and minorities makes it absurd to blame a religious group for being crushed ruthlessly, instead of the obvious giant state and police apparatus doing the crushing.
