Unfortunately the internet is filled with those who feel the only way
they can elevate themselves is by stepping on someone's head.
For me, it depends on what site I am on. I have deleted and they
LOVE that... they will friggen chase you down and whine on every
post. Face the situation head on, but not defensive. Agree to
disagree but more importantly if you're wrong, thank them.
Sometimes we post stuff that is not correct. It happens. Own it
if it does. That is respectable. If it is just a schmuck, allow him
to rant and others will come to your aid.
