Rape can never be justified. Should we be threatened with annihilation unless we rape one individual, then we deserve to die as a species for letting it go that far. Therefore, righteous anger can exist, but we mustn't allow ourselves to be influenced by it until after a logical and reasonable conviction has occurred. Then we let loose our displeasure, for if evil must exist within all, then let it be guided towards those most deserving.
People betray, kill, protest, steal, kidnap, threaten, and just in general can be rude, ignorant, or inconsiderate of others. This, I believe, justifies a right for other humans to hate them for the awful deeds they have done. Feel free to convince me otherwise or agree with me on hate rights.
In the bible we forgiven of our tresspasses as we forgive those who tresspass against us. I know there are rediculous and sick things people do but we are to love everyone. Hate is a strong word and some people have no exuse, but in some cases we don't know thier situation. We mustn't judge people but that is extreamly hard sometimes.
I like to cite Islamophobia as an example and how people mock, persecute, and condemn Muslims to this day. I'm not trying to make Muslims seem like the only victims of discrimination. However, many people suffer from this. Sometimes, you can THINK that you should rightfully hate X. It doesn't justify it.
