I'm not harmed, debate is a harmless pastime, well for me anyway, but the question seemed loaded to me. As I said I cannot, nor can anybody else, always be right, but I'd like to believe I am careful about making claims, and making sure they are based on something tangible and compelling. If I was forced into making retractions often that'd be a bad sign one would think.
In terms of this thread I'm not the one telling others expressly against their repeated assertions, what they think or believe as if they don't know, to me that is a preposterous thing to do. That's without people misrepresenting what I've said about word definitions and the value of reference tools like dictionaries. The real irony is the sheer and obvious subjective bias people are exhibiting, while falsely accusing me of it.
The ad hominem I can shrug off, we are all sometimes a little less patient and focussed than we should be, we are after all only evolved apes...
