Or maybe in years to come people won't feel the need to deliberately hurt other people?

At one time racial slurs were commonplace (intended or otherwise), but these days the majority of people wouldn't feel comfortable saying them in a public place (even if they thought them).

What was once thought of as 'looney left' PC nonsense is now broadly the norm.

I do agree that it can go too far though, such as avoiding saying that someone is dead by saying they are vertically challenged!
