Can we not use the word “retard”? it’s not political correctness to desist from insulting retarded people. Doctors are already pressuring moms to abort retarded and downs syndrome babies. Let’s show them some respect and not use them as an epithet.
You don’t have to use “retard” or any other word, and you are free to disapprove of those who do.
If you are going to set about proscribing the words that worry you, or impinge on your safe space, you are hanging around with the wrong crowd.
Those of us who live by the Constitution, including the First Amendment, take the unpleasant words and truths right along with the ones we most value and appreciate.
So I put your question back to you: Can we use the words we wish to use? Or do we have to check in with you first?
