I have been an attorney since 1982. I cannot begin to tell you the number of times I have had conversations with people who just do not understand free speech. Most of us posting or lurking here live in countries where there is some semblance of a right to free speech. In the US, the right to free speech enshrined in the Constitution protects one from government interference in one's speech [for the most part]. But far too often, people seem to have the mistaken idea that free speech means one can say or do whatever one might wish, wherever you wish, and however, one might wish and suffer no consequences. That is not how it works.
A racist, a homophobe, a misogynist, or whatever has the right to believe as he wishes. The communist, fascist, Democrat, or Republican have the same right. And anyone can speak out about their beliefs. But everyone else has the same right of free speech. They can agree or disagree about the issue the original speaker has raised. If they agree, no issue. If they don't, well, then the original speaker has a problem possibly. Yes, his boss can fire him for making racist comments, regardless of where he makes them. His family can disown him. His neighbors can ostracize him. Friends can refuse to associate with him. And that too is free speech.
In my world view, it is acceptable to hold differing political, philosophical, moral, legal or similar views. I have friends who run the gamut on religious belief or non-belief, on politics, or on other issues. But there are certain things I draw the line on - racism, advocating hatred against other based on religion, ethnicity, skin color, national origin, gender, sexual orientation or the like is different. If someone is spouting hatred of a group of people based on race, I will speak out on that. If the person worked for me, I would fire them. If they were someone who was an actor or some other minor or major public figure I would tell their sponsors, informing them that I would not patronize the sponsors and urge others to also do the same. There are certain types of speech and action I find repulsive and because I do I will speak out about them. I have never eaten at a Chik-fil-A for example. I won't patronize a Hobby Lobby. That's me exercising my free speech.
So yes, someone has the right to be a Nazi and the rest of us all have the right to express how strongly we disagree with that decision. And that includes porn actors who do something stupid, of which there appear to be more than a few.
