Only physical acts of hatred. All else falls under free speech.
Only directed and purposeful discrimination against a group. Adverse impact is allowed
Unintentional adverse impact is not okay.
Any vocal or active support for policy that would be beneficial to a "dominant" group.
Not checking yo privilege!
I will say that this poll and most likely even the premise of the thread, isn't well thought out. I am left wondering if there is a particular mind set that the poster was going for. Discrimination is not automatically right or wrong. Context plays a large part in that, and in addition the rightness or wrongness of it does not automaticaly dictact whether or not the discrimination should be legal or illegal.
