Why should I tell you what I mean when I use the word argument when you won't reply to the things I suggested you to reply to? Oh well. I'll tell you any way.
Argument - a fact or assertion offered as evidence that something is true; "it was a strong argument that his hypothesis was true"
or a discussion in which reasons are advanced for and against some proposition or proposal; "the argument over foreign aid goes on and on"
I thought that if you only knew the word argument as a synonym of debate, you could still use the context to realise that I was using it in the same way the word assertion can be used. I've used both in this thread.
Now reply to this or go to hell:

1. If a man and a woman are both 100% sure that neither have any STDs and the woman has been on the pill for over a year making all other birth control overkill, why should a man wear a condom?

2. What do you mean in your usage of the word "chisel"?
