You see, I'm sort of torn on this story.
I believe the message of White Lives matter (as a white male) is dumb, and I think it IS dumb across all spectrums in politics. Why? Everyone has equal rights according to the law to this day. However, whether it's BLM or these White Supremacist groups, I believe they have the right to protest their beliefs according to the first amendment. Whether you think their comments are stupid and offensive, everyone should be heard out, and you can make your own assessment from there to further strengthen your beliefs.
However, violence is never the answer. I am as disgusted at this as I was Baltimore, Milwaukee, Charlotte, and Portland in my lifetime (I acknowledge the KKK did horrible things that I stand against, I just haven't lived to experience it, thus my examples are ones in recent memory).
I belief these groups have the right to protest under the First Ammendment, but violence MUST be condemned.
