This has no bearing at all, but I am reminded of a cute saying....
When someone is young, and they are NOT liberal, they do not have a heart.
When someone is older and they are NOT conservative, they do not have a brain.
We all change as we grow and learn what our personal lives teach us. Another word for this is BIAS. Which is not a bad thing.
Our BIASES are what we have seen, heard, felt, and experienced in our lives.
If I see a Cocker Spaniel eating something, I know not to come up and pet them. Why, because 100% of the time, I have seen those dogs attack viciously when someone approaches them when they are trying to eat. It is my BIAS.
When I was dating on the internet, I have had the majority of women tell me they refuse to date a heavy drinker. Why? It is because 100% of them that said that were divorced from heavy drinking men, or were abused by them. That is their BIAS.
So, all I am saying is, the longer we are alive the more we experience, and the more BIASED we get.
That is because, unlike prejudice, BIAS is based on our own experiences.
...and past life experiences, which I will not get into at this time.
