In the Brave New World of Political Correctness and activist lobby groups, it has now become extremely simple to silence all opposition. The radicals do not have to mount one argument, offer one shred of evidence, or make one reasonable assertion.
None of that is now needed. There is a far easier and much more effective means to ensure that only your point of view is heard, and all others are ignored or rejected. Now all the militant social engineers have to do is throw the H word around. Piece of cake really.
Anyone dare to disagree with you? No probs. Just say they are hate-filled. Works brilliantly. You can shut up any opponent, counter any argument, and brush aside any facts or evidence simply by accusing your opponent of being full of hate.
