Critique someone's hypocrisy when it comes to respect for others and their use of dehumanizing language. Also, ask about their repeated use of the term "pond scum".
Once again...a person who advocates for dehumanization and spews a nonstop stream of hatred - who then preaches about respecting other humans comes off as hypocritical and ignorant.  (Oops, there I go again with my "deranged" "evil" "harassment")  By the way, what is with your affinity for the term "pond scum"?
