Every so often, a young or old adult wanders in here with a bunch of advice from a gifted child who's all grown up. One thing you may not understand is that a lot of the parents here have their own first-hand experiences about what it means to grow up gifted.
I agree with you that there's a bit of unhealthy comparison here on the basis of scores which are, after all, just numbers and imperfect predictors. My wife said once that some of the parents here treat their kids like show poodles.
I don't know how many parents here actually force their kids to do things they don't want to do, though. The thing about kids is that they will often get interested in things that are presented to them. Some of the parents here would be against their children doing anything in which their children weren't interested.
