Kindness is a trait. Something that is a characteristic of a person's nature - which cannot be taught, learned or practiced.
You don't work on being kind, you are either kind, or unkind. And yes, dickism is a trait of the internet - that's just the way it goes. Use the 'ignore' feature here and enjoy yourself.
Balls, I agree with you most of the time. I don't on this one. You most certainly can become kinder, more compassionate, friendlier, more outgoing through hard work and conditioning, despite the fact that you may not be naturally any of the above.
I will cut and past from another discussion on the same topic:
...
That is not kindness. That is simply choosing to do what others deem acceptable out of fear of rejection, reprisal or some other negative reaction. Kindness is a virtuous trait that is a culmination of an ingrained core of values that are part of our personal beliefs, ideas and opinions. While those things may change - a persons core character does not change.
I think we are going way off topic here, but it sounds like you are stating that a core character is made up of personal beliefs, ideas, and opinions. If your personal beliefs, ideas, and opinions can change, why not your ingrained core of values. If I practice kindness for whatever reason, why would that not change who I am as a person if I come to believe that being kind is better than being a bully?
