It is not that you state it outright but it's the way you state it that gives the impression that you state your belief as fact. By simply stating that your faith requires no evidence (which is true) you say it just is. The existence of god just is and you believe this by faith. Starting your arguments from this position you make your faith appear as fact.
There is nothing people will not maintain when they are slaves to superstition
