WHAT GOES ON INSIDE
When people say: ‘I dislike your opinions, but I believe that you should have the chance of expressing them,’ always beware.
Decades of observation, dealing with actual cases, has shown me that such people are, much more often than not, really saying:
‘I am going to say that this person has the rights I have stated. I might one day get around to trying to live up to this sentiment. But, meanwhile, I will use other means to combat his opinions: starting with making myself immune from them.’
Make a sustained study of reputedly fair-minded people before you accept their objectivity. Study their actions, and what they say to others, as well as what they would like to think they say to everyone.
