I don’t find it debating on good faith to ignore real violence by countering with hypothetical violence. Furthermore, he could easily advocate for a more hawkish view on China - a wildly popular view across the entire American political spectrum - while using his platform to disavow the real violence already done against Americans (that is also dividing us at a time when we need to have a united front against China.)
So, sure, we could do mental gymnastics to find some weird, hypothetical justification, or we could just look at the evidence in front of us.
