About homosexuality

Adultery is a morally evil act, as homosexual practices.
Sin is not a matter of written laws, is a matter so what harms yourself, people around you and the nature. There are reference to homosexual activity as an abomination in the Bible and holy books of various religions.
But also on scientific studies as harm yourself. The human body is not made for homosexual activity starting from this fact.
Sin is a morally evil act, but more specifically "an act who harms yourself" as Pope Joanes Paul II once said.
Scientific study proves that homosexual activity harm those that practice it. It is suicidal to engage in activities who hamper your life expectancy and your psycological health, there are a lot of articles here about the matter, and not all are of faith-driven people regardless what someone can think.
So say no to homosexual activity is not a matter of faith, but common sense, although faith said it is wrong previously, reality proves it is wrong.
Truth is truth, not matter if it harms someone feelings. Is our responsibility to show the truth as we cannot let they suicide themselves.
