by that definition... I think it is the duty of others to allow them to hold and express their opinion, however wrong you may think it may be.

i dont think it is the duty of other people to beleive it, or to not express their own conflicting opinion. I certainly don't think it is other people's duty or responsibility to change the opinions. It may be in their interest to, however.

But I suppose what they are getting at is: If I have an entitlement to the opinion, do I also have pretection over people trying to change it. If you have reasoning behind it then you can compare reasoning and it isn't an issue. Opinions can and should be fluid based on evidence, like scientific theory.
