Ybe an atheist

[Ybe]

You are asserting that they are faulty assertions (So what).  

You asserted that they were faulty because they were unsupported.  As a matter of logic, that's a non sequitur.  Plus, if you're saying that we should not accept atheist assertions if they are not accompanied by support, but that we should accept your assertion without support, then you are engaging in a double standard and so your conclusions also don't follow.   NOT SAYING THAT That's "so what."

  A non sequitur is a conclusion or statement that does not logically follow from the previous statement or argument
Their statements are exactly that, they don't  logically follow any previous statements or arguments, that's why I can call them unsupported.
  No I would expect support for any assertion that one wants it to be taken as more than an opinion ie as a logical ration reasonable reason.
