The Correct Definition of atheism is not what atheists are saying it is

Atheists lie when they say the definition of atheism is "I lack a belief" rather the correct definition is someone claiming "God doesn't exist."
So why do atheists "shy away" from claiming God doesn't exist?
It has been proven that atheists have NO GOOD ARGUMENTS against the existence of God. See atheists lose in debates on video here http://debatesonvideo.blogspot.com Here is a list of atheists you will see losing in debate here below
1. Richard Dawkins to John Lennox Dawkins loses
2. Matt Dillahunty (Loses to all Christians he debated)
3. Sam Harris loses to Dr. William Lane Craig
4. I debate atheists and defeat them all. We win the debates because the arguments for God surpass the lame "I lack a belief" statement that wimpy atheists such as the atheist experience show use. They will never claim God doesn't exist.....no atheist can since it is the arguments against God...that do not exist.
