When I conduct a business transaction with someone I might call them "Mr" or "Ms". No one forces me to do it. If I choose not to use these no one fines me. Its up to the person if they want to continue to do business with me if I offended them. So YES, the OP is an assault on free speech. Being rude in another person's opinion is not a fineable offense.
If you are knowingly rude or abusive, when your freedom of speech harms others, when someone is being called names and bullied in the work place or dos so to a customer, there is a problem both morally and legally. You are in the wrong.
you don't incorrectly call someone gay if you are well aware they are not. You don't call men silly girls to be intentionally rude or just make assumptions. You don't force a legal woman to use a men's bathroom unless it is unisex when she might be abused. You don't accuse someone of being a criminal unless they have actually done something wrong or that have harmed others. You don't incite harm or threaten others. You don't create a dangerous situation just for the fun of it or because you can. This is not what free speech is about.
Hate, libels or abuse is not free speech. Freedoms and right are not without consequence or responsibility. Denying the right of others is not your legal right. You right ends when it interferes with the "legal" rights or invades the person space of other.
Sorry but your "rights" do no apply to you alone but not to every other citizen.
Ignorance or your personal rejection of the law is not a valid excuse for breaking the law.
People is some areas did not believe those of color were humans or women had no rights except those a husband choose to give them. It was wrong and laws were changed and challenged for constitutionality. Same for those of different sexual identities, including those who have had legal name and sexual changes.
Free speech does not mean any and all speech. Freedom does not include breaking the law without consequence.
You do not have the right to deny others their rights and call it freedom. You are not a law unto yourself and to hell with the rest of the country and the infinite variety of people that makes up this country. You have a right to equality not superiority from the rest of the population no matter your religious beliefs. Should muslims demand FGM for all girls and women including those who are not muslim in this country. Should they demand or have the right to abuse all women who don't dress "modestly" enough for muslim men? Does one religion have the right to tell people they can't eat pork or drink alcohol or own pets or deny them them their personal choice of faith or political opinions because they believe they alone are right? If people have the right o freedom of religion in the their personal life, it does not mean you have the right to impose your belief on others of force them to follow your personal religious morality. Your religious morality does not supersede the law of the land, it applies to your personal life. If a religion believes in child abuse, they might believe it is moral in their religious teachings but legally and for everyone else in the country it is not moral or their free right to disobey the laws of the state or country.
You do not have the right abuse, harm or kill those you disagree with. You personally might disagree with someone's identity or freedoms, but you don't have the right on impose you beliefs on the rest of the country that does not share them.
Live your life by your moral code "within the law". It might be your "private" moral belief, but that does not make it your right to shove it in the face of others or make it public to everyone especially when it runs counter to the majority, counter to the law or the constitution.
You might believe killing is wrong, but for military, police and in the case of self defense there are legal and moral exceptions. You might believe rape is the right of a man or that a woman does not have a right to control her own body of make choices for her life, that does not make it correct or legal.
No one is forcing you to be gay, bi-sexual, transsexual, transvestite, asexual, hermaphrodite or intersexual, but you don't have the right to determine what someone else is or becomes.
