I'd try to teach what their values and principles should be as best I can, and if they choose otherwise, so be it.
Sorry, I don't mean only homeschooling, I just mean don't give them all that the gov tries to slap in their faces. Public schools are fine.
And working a sleazy job is part of NOBODY's dreams for their future. If soemone fails in their education then they fail at their desire to become a doctor, a scientist, a teacher, whatever. That is a failure's job to work some menial job (or someone very busy, granted.) I can see you likely practice no faith, so I shall not even respond to that comment on satansim, which is what society would get someone into.
Again, public schooling is fine, don't get misconceptions. My intent is that you are against the parents judgement. You want the judgement of society or the government (specifically in this case the ideaology of the school's judgement on sex ed being superior to parent's). A parent shall decide on such matters, not some cursed bureacrat, official, or principal (headmaster for you Euros). Can you see what I mean now or are you just pro-society??
