White Supremacy had nothing to do with these shootings.
I strongly believe the El Paso shooter was a crazy antifa type leftist disguised as a right wing hater who went all in for the cause.
I would suppose he wants to make sure that it be clear that Nationalism and Populism are not just masks for racist ideologies. That wanting strong borders and a reasonable policy on legal immigration is not an invitation for mass murder.
For too long the Left has controlled the language. They have put out there that any pride in Western Civilization and its legacy is a rallying cry for white hooded cretins. That adherence to Judeo-Christian moral teaching is an excuse to hate and subjugate others.
The public in their ignorance lap this up. The MSM ignoring groups like anti-fa just makes it easier to paint all Conservatives with the Neo-Nazi brush. It has to stop. I hope Pres Trump gets that across to the nation.
I do not think many people think their racial makeup is better or worse than others, but I do think it arguable that Western Culture arising out of the Greek, Roman, Judeo, Christian cultures has done more for the good of the human race than have others. But that is not racial. It is open to everyone. That is why the world wants to come to America, which is the result of that Western culture.
I think Trump needs to reject the concept and words white supremacy. It is meant divide.
