I quote his exact words:
"We got first-class ministers and Government, but still got
third-class citizens."

He later claimed that it was (I quote him again, same
source):
"to
relay the fact that certain people, hiding behind the curtain of
anonymity, posting irresponsible comments and insulting others,
were having the conduct of 'third-class'".
If that were the case, then that is still an admission of guilt,
because his original comments had no disclaimers or explanations of
anything to that effect. 
Simi 'misinterpretation'? If he doesn't establish the context
properly and use such harsh language, he is in fact giving no room
for interpretation. The only possible interpretation that can come
out of such comments would be 'arrogant and
condescending'.
