Remember, Trump doesn’t say things that are true - or even things he thinks are true - he only says things that he thinks will benefit him to say. So yes, it benefits him to say Jan 6 wasn’t domestic terrorism, and that vandalism of his boss’ cars is domestic terrorism.
It’s true that we evolved in response to an environment, but the actual genetic changes that allowed for that were not developed with purpose. They happened randomly, and the ones that happened to provide a benefit made those individuals more likely to have more kids that those with less beneficial random changes.
