Part of the problem is people assume thinking homosexuality is a sin, means they don't like people who do participate in it. It's why "homophobic" now means those who think it's a sin, versus those who are actually afraid of homosexual people or acts.

http://www.thefreedictionary.com/homophobic - "Fear, hatred, or mistrust of lesbians and gay men."

There are plenty of Christians who will get labeled a homophobic even if they are friends with those who are gay, simply because they believe it's a sin.

When Christians say adultery or lying is a sin and have parents or siblings or friends who commit adultery or lie, do they get called afraid of those who commit adultery or lie? It seems silly, right?
