What is the difference between white nationalism and black lives matter and who is more racist ?
I can't comment on Black Lives Matter beyond saying that at first glance it appears to be an angry reaction to real(and maybe also perceived) white racism against blacks.
I added 'perceived' since though I have no doubt of the existence of white racism against blacks, this might cause some blacks to become oversensitive and so misinterpret non-racist acts as racist too on occasion.
Now as for white nationalism, just visit stormfront dot org.
There we are dealing with open racism, white supremacy, KKK, Hitler admirers, you name it.
Storefront is big tent. White nationalists hold many differing views and don't always see eye to eye.
To be clear, I am not a white nationalist. I was just exploring the forum. But still, I was pleasantly surprised to learn that many on that forum are sXe (i.e. straight edge), meaning that they don't do drugs, drink alcohol, smoke, sleep around, gamble, etc.
It's just a shame for their racial beliefs though.
