Why do pastors and palm readers sound the same when describing the veracity of their trades?

because atheists can't make those types of distinctions and say "they sound the same", dear.

You have to provide a valid source to your claim. Many of us are not familiar with BOTH. I'm only familiar with Methodist pastors' sermons. The Methodist pastors don't just tell people what to believe. They tell their source in the bible's specific verses before telling their theological interpretation of it. It's up to the congregation to determine if they agree with his/her interpretation. Everyone is encouraged to think theologically.

Charlatanism is a profession.  
Be it selling God or fortunes. 

Why are humans so silly to buy into it? 

pastor --- a minister in charge of a Christian church or congregation.

Do you even know what you're talking about?

Because both are professional liars put simply

I'm sorry, but palmistry is not without merit.

maybe they learned it from each other

cognitive bias.
