Justified... NO!

People have different perspectives on many different issues. And that's fine, to each their own. Anyone can express their views to others, and others should be able to take it, or leave it. What crosses the line and divides people, divides society, is when any one, or group, decides to judge, condemn, prejudice, and persecute others because they won't agree or conform to their beliefs. And there inlies the heart of the issues. That person or group is constantly seeking to control / force others to their way of thinking or beliefs... and telling others who to hate. Draw your own conclusions as to what issue this applies to. Wrong is wrong, no matter how they try to justify the hate.
