There is a good reason. The Sparlock situation unveils the tyrannical, killjoy attitude of the Washtowel. In that video, they reveal that the organization expects children to obey and not be excited as children normally are--and in ways that previously were not expressible. Sure, the littera-trash did this to some degree (Young People Ask--Answers That Do Not Work). The policies did, too (no college, dropping out of high school, pious-sneering, no careers, wasting school vacation in field circus). But, this video puts it in the language that most people instinctively understand. This is why you are going to continue hearing so much about it--and it will continue, because this is much more than a Sparlock issue. This is a fun-issue, an issue about stealing childhood from those who are born in. Many can relate to this, especially those who were born in.
Unlike this, the "A generation" issue only attacked a doctrine. College only attacked one facet, not the whole childhood experience. The generation issue dealt with the instability of washtowel doctrine, not on personal effects on children. Danny Haszard demonstrated what happens when the witlesses are too pushy, and what risks they are taking on when they continue pxxxing people off. However, none of these things touched people the way Sparlock did. Sparlock is about ruined lives, ruined childhoods, lost opportunities, and that being one of Jehovah's Witlesses means no fun. As such, I suspect you are going to be seeing more posts about Sparlock long after it "should die out".
As with any topic you do not have interest in, my suggestion is simply not click onto them. With the exception of moderators who have to go through everything, we have the option of skipping topics that do not interest us. Many of us who were recruited were not touched in such ways by the Sparlock fiasco as those who were born in, and those whose parents were more liberal were not as affected as those whose parents were strict. But those whose parents managed to snuff out every bit of fun from their childhoods, who had to pious-sneer every school vacation, who never got to make worldly friends, who lost class trips for the religion, who never got to do anything but field circus after school, who missed college, who never got to listen to real music or watch real movies or TV (or, these days, YouTube videos), who were stuck with their noses in the religion from the time they got up to the time they went to bed, Sparlock represents them. Caleb is what they could not express in their own lives. Yes, those of you who were not immersed that deeply will probably be bored. But, for the sake of those whose lives were so tightly bound by the Washtowel, let's continue putting up with this and accept that this topic is not going to die out.
