And please, I am just trying to understand the thought process behind this. Reddit sucks and I pasted a verse from sefaria and it broke my post so I have this as a quote instead of rewriting it from scratch.
I see plenty of posts by Jewish atheists asking if they are considered Jews still and everyone says yes. But in Torah it is very clear that they are not Jews because they are cut so why do we make this exception when people ask? You have verses like in numbers 9 that say if someone refrains from making an offering on Pesach, they are cut off from our people. I get this is talking about a sacrifice. So if we have our temple, will all these atheists who reject passover just all of a sudden not be Jews? And what about exodus 12? This also claims that if you eat chametz during Pesach you are cut off from Israel. I am sure atheists are not caring about what they eat that week so I would think they are “cut off”, so why do we say they are Jews still?
“Seven days you shall eat unleavened bread; on the very first day you shall remove leaven from your houses, for whoever eats leavened bread from the first day to the seventh day, that person shall be cutoff from Israel.”
