Standing up for constitutionally guaranteed rights and freedoms such as freedom of expression is not "racist stuff or enticing hatred".  And it absolutely is free speech.  

Feel free to criticize my views if you wish.  I may disagree with you but not with your right to do so.  What I find abhorrent in all this is that people are losing their jobs, being pressured into resigning, and sent to sensitivity training for publicly espousing views that are, in my view, perfectly defensible and far from controversial.  Yes, the victims here are white people.  But so what.  They are still victims.
