During a match or race, this is such a valid question. 

During a debate or a conversation though, no other question can be worse off. 

When stepping into a debate, the intention is to discuss, put your point across and listen. Perhaps refine your view, or establish it even further in your head. 

More importantly, it gives food for thought for those on the fence. The half informed, the ones still deciding, the reluctant, the evaluating crowd. 

Don’t try to convince the other side that you are right. 

Don’t try to win conversations 

Try to have one instead
