If you hear an ass braying out in a field, do you have any particular compulsion to start braying BACK?
Of course not.
The world (and thus this forum) is chock FULL of a variety of different people: MANY are thoughtful, intelligent, knowledgeable, and seeking more of same. Some with childish impulses and arrested developments who might be intentionally contrary. Don't get angry, get bored with it and click "ignore". Eazy peazy. That way any intentionally irritating person ends up talking to themselves only.
