I think it's somewhat lacking these days.
I see a lack of it everywhere:
The way people relate to one another
The way people drive
The rubbish thrown away in public spaces
The trashing of our natural environment
The shouty politics
Cruelty to wildlife
What do you think?
I personally think the world would be a much better place if respect for everyone and everything, however different to us, and differing their views (if human) were taught to children so that they could grow up to be respectful people.
