I don't care what you do. If you want to use evidence to sway people your way on a opinion thats your choice. I wouldn't say that is manipulation. if you see both sides of the coin equally and make your own choice of opinion based on that, that is not manipulation. If evidence is fake or covered up that would be manipulation of opinion (our goverment does this alot).
Judgement and expectations are responsible for 99% of man's misery. See how my judgement of the situation I find myself in makes me annoyed?
