Sarah Huckabee Sanders was refused service because of the actions of the Trump administration separating child immigrants from their parents and putting them into concentration camps.
Trying to justify what happened to Sanders at the Red Hen undercuts the argument that refusing to serve gays in restaurants is discrimination. To argue for both is hypocritical.
We should not being stooping to their level.
Don't be silly, while denying service to gays because they're gay is discrimination the attacks on human rights criminals is justified. Just like the fact that the violence of the oppressed is not equal to the violence of the oppressor, the same can be said for justice.
