Is freedom of speech only accepted if we agree with the speaker ?
That is a huge question Annie, for sure. But there are things which are clearly illegal, incitment to violence is one. And yes, it is very difficult- this concept of 'tolerance'. I do consider myself to be very tolerant, but I am 100% intolerant of racism and cruelty to children, animals and those who are weak for some reason, rape and crooked Politicians who commit fraud, and some more...
Some things must not be tolerated, ever.
I have had many arguments with French friends, including 2 who are quite famous cartoon artists- about the right of speech by Charlie Hebdo, etc. The violent death of some of their contributors was totally abhorrent- and I will condemn it with all my might- but they did choose to offend for the sake of offending, and I will not condone this.
