Rather a lot of whites are in the angry violent mobs (gay, muslim) that you mentioned.
The whites in these violent groups are by and large Marxists. They are one of the enemy of the compliant working stiff. Muslims aren't necessarily white. They come from all races.
Any group that attempted to stick up for the middleclass defending against the wholesale theft of our wealth by government would mostly be white. You might get Asians to rally. You might get some maverick Blacks to stand with you. You can count on one thing, all the other groups would call you white supremacists even though it's values that are the object.
