I have done so in the past and will certainly do so in the future. That is the intellectual mindset. Also, I can point to specific and demonstrable reasons why I hold my beliefs. I have them because they have survived challenges and shown themselves to be valid. Religious preferences can't claim any of that.
Nobody can show any evidence that suggests the existence of any deity at all.
Nobody can even show a reason why any one deity should be preferred over any other. This doesn't change the simple fact that there is no resolution of the question of God's existence, and any belief or non-belief in God is merely a personal choice. If they did, there would be no religious strife and no debates over the topic. They would not see any need to question or attack the theories of science. They would be willing to freely and easily discard or modify their beliefs in favor of something better.
