If you want to believe that belief in external reality to your senses requires a similar leap of faith that belief in unprovably extant supreme beings requires that's fine, but that's not what the word atheist means. That's not how people use it. They don't use it to refer to people who refuse to believe in things requiring faith (as in believing in something that can't be proven). It is used to refer to people who don't believe in gods.
This is so untrue it hurt my brain to read that. Realists and atheists aren't the same thing, first of all. There is some overlap for sure, but they're not equal.
Secondly, you apparently have zero clue what the word "worship" means. I get the point you're trying to make though.
"Obey" seems to be another word you struggle with.
And demanding people recognize reality is pretty fair. We don't demand you to believe it not believe anything one way or the other about supernatural issues, but while we may have different ideas about what reality is, we can say that everybody's existence does have some things in common and I think it's fair to presume any sane, competent person can agree on that much.
Theism is a pretty specific term, implying a belief specifically in (a) supernatural being(s) of some sort. Having a belief of any kind about anything is not tantamount to being theistic.
