LOL you said you are not going to tell your parents why? because you know you are doing something wrong. You know your diabolical act of being gay gonna hurt your parents' feelings. You know you are bringing bad name and shame to your family.you know you are seriously threatening your parents' integrity in a society. You know the sky is falling upon them once your parents happen to know your gayness or sexual orientation (sounds less filthy than you are) LOL. 

Homosexual behavior not only seriously harms homosexuals individually, it harms society also. Let's start by looking at the health of people who engage in homosexual behavior:

People who practice homosexuality experience higher rates of many diseases, including:

Human Papillomavirus (HPV)
Hepatitis A, B and C
Gonorrhea
Syphillis
Gay Bowel syndrome
HIV/AIDS
Bacterial vaginosis

People who practice homosexuality have higher rates of:

Alcohol abuse
Drug abuse
Nicotine dependence
Depression
Suicide
Domestic violence (20 times more common than among heterosexuals)

Ah, but maybe these problems are the result of society's discrimination against homosexual people. Not true. If we look at places in which homosexuality is accepted, such as The Netherlands (gay marriage is legal there) and San Fransisco, we find that the greater the acceptance of homosexual behavior, the higher the rate of the above negative consequences. Accepting homosexual behavior makes it worse!

What about the effect of homosexual behavior on society?

In addition to a domestic violence rate that is 20 times higher than among heterosexuals, these are some of the negative effects homosexuality has on society:

Higher rates of child molestation*
(Nearly 1/3 of the child abuse cases are homosexual in nature, and homosexuals are only 3% of the population.)

Daughters of lesbian "parents" are more likely to engage in risky sexual behavior and experience the consequences of that behavior.

In areas in which homosexual marriage has become accepted (The Netherlands and areas of Scandinavia, for example), the fundamental building block of society--the family--has fallen apart. In some of these areas as many as 80% of the children are born outside of a family.

Children of homosexual "parents" do the worst in 9 of 13 acedemic categories when compared with both married heterosexual couples and cohabitating couples.

Homosexual behavior is linked with higher rates of promiscuity, physical disease, mental illness, substance abuse, child sexual abuse and domestic violence--all things that impact society negatively. Don't try to say homosexual behavior doesn't hurt society--it is a major force that tears down society and harms children.
