Okay okay, he's racist...to you, he's not to others, we're not obligated to use your racistometer, okay?
Racism used to be and should be very clearly defined, that has changed because it is easier to smear someone's character when you can take irrelevant "no smoke without fire" examples and then brandish absolute terminology (racist, sexist etc.). Occasionally not even bothering with that irrelevant starting point and just making baseless assumptions.
It is maddening that people doing this are the loudest voices on the left, I genuinely think it is one of the major reasons the right are winning elections, winning referendums and laughing at us whilst they do so. The truly frustrating thing is that if these loud voices stopped the baseless name calling and character assassination, stopped the identity politics (white privilege, male privilege being key) focused on class privilege we would get the job done without alienating millions of potential allies. It would also allow some coherence and actually focusing on the issues in a debate, for example pointing out that when Shapiro talks about how GD and GID were very recently being classed as mental disorders that he totally ignores evolution in psychology, rather than just shouting what a bigot he is.
If you were a young undecided voter and you see one of those videos of "Shapiro destroys SJW" I could hardly blame you for believing you will relate much more with the people on the conservative side of the spectrum.
