Why We Can't Accept and Respect Other Peoples Opinions?

I am not saying to believe everything or react to everything that comes to you, but if its comes to you in the form of criticism or even a suggestion why do we always give negative feedback? and believe me NOBODY have to waste their time trying to help you. I do not allow anyone to take my blogcast radio program over by dis-respecting my listeners or my guests. Therefore that will eliminate any confusion, and avoid aprogram takeover.
