Udayana,
No-one's saying that the (lawful) right to object should be restricted either, but why should someone have redress because they've been offended?
My point was that if someone feels that they want redress for being offended they should have the freedom to argue for it.
As to whether redress may be required, it seems to me that it's possible to claim that offensive behaviour has similar effects to targeted bullying, harassment and other victimisation, particularly wrt. mental health. Also, much ridicule relies on gross generalisations that potentially stigmatise whole communities, giving rise to discrimination, violent attacks and other issues. It is not as if speaking has no consequences or feelings are not important and don't matter.
