Why does the Biden administration refuse to use the term “illegal alien” ?

For the same reasons he avoids the fact his ancestors were slave owners.

Because you republican have turned that perfectly acceptable term into an evil racists term .

 Some words that are spoken by evil such as sieg heil are innocent words but because of hitler they are no longer acceptable to everyone but the communist and the ugly red hat trump supporters .

Illegal means against the law. Illegal alien or immigrant means someone who did not enter as our laws require.  Truth seeker has no idea what he’s talking about. He will simply argue anything and make up stuff.   Libs have long, twisted words to suit their agendas. “Illegal”  obviously has a negative connotation since it means against the law,  so they don’t want what they’re doing to be seen as “negative” or illegal  by the masses.    They are vile conniving people, or maybe just real ignorant. “All votes are legal” and citizens or “non citizens”???  Yeah...ignorant. 

Because accuracy and honesty are not Democratic Party values.  By changing the language, they know they will fool the idiots into forgetting that these illegal aliens are foreign nationals breaking our laws to be in this country.

Because there is no such thing. People are not illegal. They are either citizens or non-citizens. 

Because aliens haven't landed on earth yet...or have they.  Biden also never uses the term legal votes as all votes are legal.  Oh excuse me I did hear that a few republicans in congress are being investigated with extra voting ballots and envelopes and such, and that during investigations of "voter fraud" they have discovered a few republican voters that have voted for Trump twice.  

Biden's now pushing the USCIS to dispense with the word "alien". It's madness. There is nothing insulting about the word "alien". It means "foreigner". Shall we dispense with the word "foreigner" as well? Will that great band from the 70's become known as "non-citizen"? Imagine Japan or Singapore contorting their respective languages like that to accommodate criminals.

Dunno.  Why did the Dump admin refuse to use the term "right wing domestic terrorism" ?

Could just use the term invaders
