You can't say that teenagers are just as responsible or fully grasp the consequences of their actions. Their bodies aren't fully developed and neither are their minds. Think of how you were ten years ago. Were you as smart then as you are now? No, you were an idiot. You are just as big an idiot now. It is only going to take you ten more years to realize it. I think this is true for everyone.

If you want to legalize consensual sex among teens why not let minors drive cars, smoke cigarettes, and join the army. They are apparently old enough to understand what they are doing.

As for spelling, although it is considered low to insult someone's spelling and grammar, all standardized testing uses spelling and grammar to measure intelligence. It is basically a subtle way of insulting that. Don't get me wrong "i,m" not saying you are stupid. Just use spell check in the future it makes it easier to read.
