But every statement of opinion is inherently two sided don’t you think? By saying that you are in favor of anything you’re also saying that you aren’t necessarily in favor of something else. For example if you loved every flavor of ice cream then you’re unlikely to say unprompted that you like rocky road ice cream. Because there would be no point in singling out that flavor if you thought they were all equal. Just like if you thought all humans were born with an innate ability to drive then you wouldn’t specify men. I understand that in this case he was just using a saying that he’s probably heard somewhere but if someone hasn’t heard that saying before then they might be looking at it from a different perspective and to them it sounds biased or prejudicial.
