I disagree with your example. I know it's only tangential to the topic being discussed, but it's quite important, so I'll elaborate. I used to be anti-gay. So, in PG's words, ~P (why did he choose "~" instead of "!"? ~ is bitwise not in c++, while ! is boolean not. It's going to remain one of the mysteries of life). Now I'm not only pro-gay, pro-trans, etc, but thankful that I live in a country that is free, and gay and trans people, and all people, can decide for themselves what life they want to live, and to consider that they don't need approval from the rest of the society, or actually, that the rest of the society owes them an approval for their life choices. But why was I anti-gay? Because that is what I learned as a kid. Kids learn from adults. Especially during teenage years, they are rebellious, but in reality, they still take their value clues from adults. And once you are an adult, and hold some values, it's difficult to think that they values you've held all your life were wrong. So you come up with excuses. Like the Bible thing. I grew in an atheist society, so that was not my excuse. My excuse was simply that I was raised thinking that it's wrong to be gay. That was it. In time I changed my argument into "Gay people want to get marriage benefits from the government", but someone pointed to me that gay people pay taxes too. So, after a while I realized that whatever arguments I had were hallow. But most people don't go through what PG call the journey from ~P to P. Their brain doesn't allow them too. Find a way to help them.
