"if an online discussion (regardless of topic or scope) goes on long enough, sooner or later someone will compare someone or something to Hitler or his deeds."

Sorry I used it literally instead of trying to find loopholes. What interesting is you used Leopold, Hitler AND Trump??? in your comparison of the Apartheid era government.  That like Godwins Law to the power of Three! Maybe a new record or a new "Law" required here? 

The point is when Hitler (and now Trump, who hasn't killed anyone or thrown a black man out a window yet) references are used so casually you lose credibility. This wasn't a discussion about 'great evils through the ages' it was a discussion about apparent Apartheid profits.
