I clearly said it was 'stupid' and 'offensive'. Right there. Just a few paras up, where everyone can see. What's the word we use to describe when someone lies or misrepresents in front of others, whereupon their lies are easily debunked by anyone, immediately so that everyone is aware of those lies right in the moment? (Donald Trump does that, BTW) Almost nobody actually likes the truckers, that's besides the point.
