I'm getting pretty old but I never thought of the word "negroe" as being a pejorative. The word "gay" meant to be happy, cheerful, joyful, and lighthearted. Now it is used in a way I would not have recognized years ago. How will we be able to communicate in the future if common words spontaneously aquire different unrelated usages.

I haven't seen any of your posts LoL

It depends where you are being misunderstood. If you post something tongue in cheek, but in a serous group such as Philosophy or Freethinkers, they will mistake it for a real view or position ...however if you post the same thing in humour it will be seen for what it is ...a joke.

I have also found that atheists are a generally angry crowd.
