"The alternative is far worse", with us currently being in a state of world politics where whoever shouts the loudest on social media gets to set the agenda.
Freedom of speech is a fundamental human right. No ifs or buts about that.
In the same breath, it is very important to realize that your freedom of speech does not absolve you from responsibility for what you say. It does not obligate others to facilitate your speech, it does not entitle you to any platform you wish, and it does not obligate anyone to listen to you.
Similarly to the second amendment, which enshrines your right to own weapons (being the foundation of a well-regulated militia and so on) does not obligate anyone to provide you with weapons, nor the facilities to train with and maintain weapons, and it certainly doesn't require anyone to admit your onto their property if you are currently holding any weapons.
