I don't think anyone claimed that a government protection was being violated. It's you that saw "free speech" and apparently assumed that meant the first amendment and the US government. There are ways in which I can legally attempt to suppress the speech of others, for example I could threaten to evict guests from my home if they bring up certain topics. That is clearly an action which goes against the principles of freedom of speech but it is not a violation of any of the protections provided by the US government. Whether such an action on my part is morally justified will be highly context dependent. For example, perhaps I don't want certain topics discussed in front of my children in my own home?
