OP, I will say this, it does seem that you are learning here and starting to "accept" others opinions and advice -- not, of course, that all of our advice is worth listening to...
I applaud you for that. When you first started posting, I and many others, saw your attitude as a bit brash and argumentative, or worse. However, in reading your responses in this thread(the last few), and in your "becoming a trainer" thread, it does seem that you have taken a step back and realized that NONE of us have ALL the answers. You have taken a large amount of criticism and learned from it(at least I think you have) and this will certainly help you become a better horseman/person/whatever in the future.
It isn't wrong to have or even express your opinion. But, the way in which you choose to express it and interact with others is very important.
And, lastly, it is always(used this word for a bit of humor..) better to avoid lumping an instrument, technique, method, style, etc. into a blanket statement; i.e. - "..bits are cruel..."
