Parents do not always know best, particularly when it comes to sex education. Parents cannot be trusted to instruct children effectively in sex education because they themselves are often uneducated in the matter and have personal biases regarding the subject. [1] Often they will not understand the finer points of contraception and STDs, things that have each changed substantially in the past few decades, with things like the morning after pill becoming readily available in many countries, and diseases like Chlamydia much more prevalent in populations than they were in past generations. [2] Parents’ ignorance may thus misinform children to their detriment. The parent may not understand their child best preventing their children from ever developing a meaningful understanding of their sexuality. Such is the problem for gay children raised in homes that say being gay is sinful and unnatural. [3] With the only authority figure on the subject he knows telling him he is defective, a gay child is left to suffer and wallow in self-loathing.  [1] Farrell, My mother said…, 1978.
