Yup, this is what real parenting is all about, passing on the correct morals so that children mature into responsible, understanding adults. Congratulations for both of you for raising a big family the right way even if they are a pain in the ass at times
You know, children are not naturally intolerant. They are usually shy but once that is overcome they welcome everybody with open arms and ignore all the silly stuff like race, religion etc. They learn intolerance from others and it is up to parents to overcome this and keep them pointing in the right direction.
