Why don’t we treat homosexuality like we treat smoking?

PF-cigarettes_1383528cOn barbwire.com there is a well-written post asking a valid question: given the health risks associated with it, why do our governments not treat homosexuality the way they treat smoking? Why do they instead impose on school children sex ed curricula that teaches them to view homosexual behaviour as harmless or normal, or even encourages them to experiment with it??

As the article points out, homosexual behaviour on average reduces the life expectancy of those engaging in it by 20 years. Is this really what we want for our children?
