I agree. I think people who eat fairly healthily and do #2 daily or every other day don't need to cleanse, but it doesn't hurt if they use safe and gentle methods every now and then.
Anyone doing #2 only every 3-7 days is constipated or has a sluggish colon and should cleanse. I think the methods used are what I would debate.
