Should Americans be required to have a REAL ID or passport to fly domestically?

They can just explain that they are here illegally and can't get any of the required documents. They will be waved through and probably upgraded to first class.

They will not be upgraded to first class.  
But the rest of your post is likely. 

Why would it be applied to non-citizens? They aren't able to get one. They would have to use a passport or other form of acceptable ID as they currently do. You can check the TSA website for what's acceptable. If you're making some point about undocumented immigrants, I expect that being undocumented means they will have to travel by Greyhound.

Why allow illegals to simply have a border crossing paper? But require citizens to go through extra BS? 
We have a no fly list. 
This another avenue for government control
 To force citizens into following their commands. 
No shot, no flying, owe taxes, no flying. Protest the gov, no flying. Etc. 

I don't think you fully understand what a border crossing card is. And, if you didn't notice, I more or less agree with Real ID being unnecessary and as I pointed out elsewhere, my state and many other states agree. That is why this law has taken 10 years to go into effect and won't even be fully enforced until 2027. Who knows? It could even get struck down at some point.

She does not understand what a crossing card is, but I have educated her on this in my comment above.

I agree.  Even if you were going to fly, I believe a valid passport is acceptable if you don't have Real ID.

EDIT:  Acceptable forms of identification:

I think the question was edited to include passport. It would not benefit the tourism industry if non-citizens couldn't fly domestically with an ID that only Americans can get.

Yes, the question WAS edited which makes some of the responses irrelevant.  Not the first time this has happened.  

It wouldn't be so annoying if she had acknowledged her edit. I'm still not sure what she's getting at and we know there's always an underlying reason, not just asking for opinions, but rather looking for opportunity to give us her opinion. Maybe it has to with the government tracking citizens. Minnesota delayed implementing real ID because of data privacy concerns. This law was supposed to go into effect years ago and I recall renewing my passport in case I needed it to fly somewhere and my DL wasn't enough. Apparently many states weren't issuing them and in fact, the law won't be fully enforced until 2027 for that reason. But it doesn't explain the comments about non- citizens, which I don't understand.

There was no edit.

The comments about non-citizens points out one's disdain for anyone not born in this country, particularly those from our southern border.  It must be nice to know that one's forefathers arrived here on the Mayflower.  Can you imagine how the Native American tribes must have felt when all those white people showed up on their doorstep without an invitation.

No, the passport part was there from the beginning.
