Hi Mate, you see that's the issue.....people can't explain their prejudices because its learnt from such a young age! The alternative is to tell people and let them figure it out for themselves. I'm sure you're a decent person and have no reason at all the think you are not a loving and kind parent/grandparent or both, so reading that article - what are you scared of....what grabs you by the balls and and makes you shit scared? What do you think is happening?
Surely its not that difficult to explain?
