The point is the terrible ease of applying a double standard in how you approach an issue.
Some private actor X performs an action Y which other people Z find reprehensible. The action Y is within X's legal rights to perform.
You can focus on how reprehensible Y is and how Z are right to condemn it. Or you could focus on how X should be totally free to do Y if X so desires, even if we don't like Y.
What usually happens is that if you feel Z are right or you wish to support Z or you wish to not be seen as supporting "enemies" of Z, you will focus on condemning Y. It won't even occur to you to emphasize that doing Y is legal; if pressed you'll freely admit it is, but to you focusing on how Y is legal will look like hypocritical attempts to evade the real issue, which is the terribleness of Y.
On the other hand, if you dislike Z or like the "enemies" of Z, you will focus on how Y is legal and how Z's dangerous rhetoric about Y poses a real danger of conflating Y with actually illegal acts. You might or might not agree that Y is terrible, but to you it will seem a decidedly minor concern compared to the dangerous rhetoric issuing from Z.
