    I do love the manner in which you have presented this specific difficulty plus it does supply me some fodder for consideration. On the other hand, because of what I have seen, I basically wish when the comments stack on that people today keep on issue and not embark upon a tirade of some other news of the day. All the same, thank you for this outstanding piece and whilst I do not really concur with this in totality, I respect your perspective.
