@KaySpence,
umm, 13 year olds are having sex, but god forbid they might hear anything about it, especially something that might help them, or something that might make them say, "hey, maybe this sex thing isn't all it's cracked up to be" (we've had a few young kids come here with legitimate problems (pregnancy, abuse) who've gotten some great help and contributed good threads)
and as for politics, you're right, why would you want a 13 year old to know anything about politics, i mean just because they're going to be voting in 5 years and deciding the countries future (or maybe if we keep them sheltered they'll not vote at all)
as for childish and nonsensical questions, nonsense, most message boards (including older posts here) have had the same questions asked, many if not all asked by adults
