Bull! If it were recent or immediately relevant then yes I would agree. But this is a slippery slope situation because people change, situations change, and none of that is relevant to a situation where a person reacts on instinct. If there were racial posts insinuating that it was ok to target X group then ok, that may be relevant, but not if it was historical. Use it to establish a bias, use it to establish character, but in no way shape or form should that play on the guilt or innocence of a person. Sentencing... maybe. But it truly has no bearing on the situation. If a radical, outspoken, neo-nazi has an African American Muslim kick in his front door to rape kill and destroy the guys family and said neo-nazi shoots the intruder, then the fact of it is that a MAN defended his home from another MAN who intended to do harm. In this case, it was a mistake, but everything supported the fact that it was a mistake of location. There was no racial or other motive, so why push the BS. It should be denied.
