If, after said re-evaluation, you've come to that conclusion, then that's fine. You can be content with the fact that your position is sound and the people who disagree have no rational grounds for it, and are just assholes.
When you skip that re-evaluation step, stick your fingers in your ears, yell "la la la" really hard, and then cry because people are "being mean to you" while refusing to acknowledge that it's because they don't want your ill-considered, over-engineered crap making their lives difficult for the next decade, then that makes you an asshole.
