I believe that people should have the right of freedom of speech. However, it also means that you should have the freedom of speech to argue against them too.

I believe that people should have the right of freedom of speech. However, it also means that you should have the freedom of speech to argue against them too. (However, if you wish to state your view, it would be better to try to make an argument for it, if you can do so. (It is possible that it is just a guess, in which case you can say so; if you know why you made that guess then you might mention that too.) If a reasonable argument can be made on both sides then a better debate will be possible, rather than merely being ignorant and saying things without any good reason to do so. If you actually explain things, then you can learn better, isn't it?)
