Freedom of speech is a principle that nothing to do with laws at all at first. It is always an essential component of scientific inquiry for example. It is not optional here. There is also the freedom of association, so you do not have to associate with people whose opinion you don't like. Many countries have laws that disallow you to disturb the public order. These are old laws that aren't based on any principle aside authority, vanity and perhaps a little practicability in some situations. They should be improved. Blasphemy is illegal in my country. This law was not applied for decades and is therefore more or less invalid. It just hasn't been deprecated because laws do so very slowly without much incentives for public officials. So basically blasphemy is legal now. I would argue with the inception of the net and internet comments, offensive speech is legal too.
