You don't, because homosexuality isn't bad at all.
You shouldn't try to convince them because all people are entitled to their own beliefs and morality.
No, homosexuality is natural for many people.
Bad attitude. Convince them with money.
Nothing... The problem is people having a problem with homosexuality
No idea. To encourage people that homosexuality isn't bad? Is there really ever a purpose for any films?
No, people are born homosexual. Nothing "causes" homosexuality.
They explore homosexuality
Nobody chooses homosexuality. It's something that some people are born with.
convince
The term "advocating homosexuality" is generally used by people who oppose gay rights. It is the mistaken belief that you can encourage people to be gay, which is impossible.
It is neither good nor bad. Some people are born and are attracted to people of the opposite sex. Other people are born that are attracted to people of the same sex. Provided any sex that happens is between consenting adults, it is no business of anybody else and societies err when they make judgements on the issue.
Because homosexuality doesn't matter and people just don't care about it any more.
Homosexuality isn't something that needs to be treated. It is how some people are born not someto disease.There is no changing it.
