I've had two such chats with Trump supporters, and one said in great detail that this statement is true. He acknowledged that Trump has done a number of ethically and legally problematic things, and that supporting Trump means enabling this, but feels that he has to accept that necessary evil in order to achieve his policy goals on various issues. (The other flatly denied that Trump has ever done anything wrong and refused to keep talking when I produced examples of the most pointlessly cruel stuff.)
Have you heard differently in your own casual chats on the topic?
