Because it doesn't really say much of value. I can break it down tho
"They think just because you can't see, feel, smell or hear god he doesn't exist."
You begin your post with the above part, which doesn't make a lot of sense. If I can't prove the existence of something, why would I believe it exists. Nevermind the fact that has been 100s if not 1000s of supposed Gods throughout history and the definition of God differs from person to person, culture to culture and so on.
"Some atheists are very bright but I think majority have suffered some trauma which caused their belief in god to dissipate."
This is like saying religious people are ill and deluded to belive in an unprovable God.
"Little do they (atheists) know, their belief in god not existing is similar to those who believe in god's existence. Everything is based on trust in your personal beliefs."
How is it similar? Either God exists or it doesn't, there aren't multiple ways around this. I can believe in flying unicorns, doesn't mean they exist (unless we get solid confirmation of their existence).
