A lot of people may argue that before the age of 18 you really do not have the "psychological" capacity to make such "desicions". The argument with teen pregnancy does not stem from it being natural or not, it stems from people (call them kids, or adults, pre-adult, post-tenn, whatever you want) under the age of 18 are still doing several things, which mainly are: living at home with mom, dad, or both; still in school; do not fully support themselves (financially, etc); and that they usually are not 'prepared' in the 'conventionaly way' of 'having a child'. I put all those in quotes because they really need to be defined.
Comparing homosexuality to either teen pregnancy or religion is a bad comparison, because you are doing two things, and one is; when it comes to teen-pregnancy you are forgetting that most teens get pregnant mostly due to unprotected sex because of the psycological feeling that most teens will go through what educational psychologist would call risk-taking behavior; a sense of feeling like it won't happen to me, etc. Other reason for teens and pre-teens getting pregnant are molestation either by an uncle of father or step-father. Other reason as to why it is a "hot topic debate" is because of the costs to tax-payers. In 2004, taxpayers in all 50 states paid out over 9,009 Millions of dollars, with the lasrgest numbers coming from our most populous states and states filled with the most minorities (demographics) such as, TX, FL, NY, and CA.
As for the religion argument, you are comparing apples to oranges. I see you are using it as the basis for it being Constitutionally protected, when in fact it already is protected. It is not against the law to be in love with a member of the same sex, or be homosexual. Nothing in the Constitution prohibits it, although I bet you meant to argue for laws to be put in place that would protect 'spouses' of homosexuals, just as there are for male and female spouses. The reason religion is protected, no matter how grotesque or odd it may be (you can even sacrifice animals if your religion permits it, just not your neighbors dog
), is because the founding fathers were from countries which persecuted religions against the state run religion, such as England, France, Spain... and even when the colonists got to America, they too persecuted religions which were different than their own (ie: puritans and catholics). Also, the constitution protects religion from becoming state regulated and ran, hence the no-establishment clause.
I must have to disagree with your final statement about it being "unnatural" in the "arbitrary societal conditions that we live in under precluding self-sufficiency until at least adulthood at age 16"... now, granted most of the stuff you said is what I call word vomit and could have easily been said by stating simply: we (gov't) say you are an adult at age 18. Truth be told, in our society, most 15, 16 yr olds couldn't make enough mney to 1) support themselves, and 2) support a family. Last thing I want is someone who hasn't been in the work force making decisions (ie: voting) that affect my life, as well as my pocketbook. I also do not want someone who has no sense of the world outside of their own egocentric life in which they live in. To give examples from history, in Sparta you weren't even a considered a citizen until you served in the military from the tie you were 7 till 30 yrs old.
THEN you got some privilages, and this was over 2500 years ago!
Sorry for all the writing, but I serisouly think that this society puts too much focus on ME (I) than on the WE (US, or in democratic-republic society the majority). What is good for all of us is never able to be accomplished because of the differing of opinions, beliefs, society we grew up in, etc etc etc (you get the point). In this huge world we live in we sometimes feel like we get lost and the we are not heard - "My voice is not being listened too and I got something important to say!" I have to say we should still stick to the majority rules; special interest groups only speak for a minority of the population (and I mean all, including those like oil, big business, etc) and do not take into consideration the entire populous.
Just my views.
