It's when ur roasting them and they start saying nasty crap, and when u tell them to chill they say "freedom of speach"
Freedom of speech protects you from legal prosecution from what you say, but you may face prosecution from the people. The aim of freedom of speech is to stop government intervention AND let you state your opinion without being harassed or physically assaulted by the people. A reporter named Lauren Southern was assaulted a few months ago for saying "There are two genders" by retarded feminists.
That punishes people, it doesn't actually prevent it from happening. Watch any video of someone talking out against feminists or social justice warriors, 9/10 someone gets harassed or assaulted.
Of course assault laws punishes people, that's the point of the law... And can you prevent stupid from happening?
