Exactly. Scientific history is full of these contrarians who presented evidence to show they were right and everyone else was wrong all along. Now, to be respected in the scientific community you need to present strong evidence, even better irrefutable evidence, if possible, so as to not be viewed as a crackpot. In other words when going against the grain you'd better have an airtight case that's credible. Even if it eventually gets shot down, which happens, you'll have wanted the scientific community to have learned something in doing so. You'll still be remembered for that.
