On reflection, I think I'm at least partially lost in this, again.
I think I understand what Makwa and Michelle are saying. I'm just trying to explain a bit to the poster why he's asked to leave, without getting into another endless discussion. Hence the statement- 'this quickly leads to [another] what is racism discussion.
As to the opening post- I thought it was being ironic only. I can see I'm likely to have been wrong. And even if he was being ironic- irony is 'awrany' on-line... so people will take it as a literal invitation.
So maybe it should be withdrawn?
