I think I explained much the same thing (though Bob did it much better

...) in the BS thread. Suppressing freedom of speech is never a good thing, especially when adults are involved. Nevertheless, I also believe every effort should be made to avoid people going overboard and attacking others, as it happens all too often.
I readily admit to being more sensitive than the average person, but this is the way I am, and I'm afraid I'm not going to change at my ripe old age. However, some people were really extremely unpleasant to me in the past, especially when I was dealing with difficult situations in my everyday life. It's true that most people come back to the site after having left, but this doesn't mean they forget such episodes.
