I have to go with the sheep thing.
Well if you must, but it’s born out of arrogance. ‘I’m right and everyone who disagrees with me is a sheep’. You’re elevating yourself above the people who hold different opinions, and thereby shooting your entire argument in the face.
If you want your opinion to be taken seriously, you should afford others the same respect, rather than dismissing people who disagree with you as part of a witless, ovine conspiracy.
