The founding of the country would be one, unless you believe the US constitution was derived specifically from black muslim principles and written by asians.
And if you haven't noticed, at this point in time, the only institutional bigotry remaining in the US is against whites and males.
Here's a wiki link with some examples of that:

And what about non-institutional bigotry? Is that supposed to be somehow acceptable or desirable?
How about this: f-ck all bigotry—institutional or otherwise.
And how about this: f-ck all racism—institutional or otherwise.
Can we agree on those as a starting point?
