Any evidence to support this, or just a typical internet rant that could be completely made up and has gained traction from others who don't like him ?
Maybe he was rude, but then again, maybe he was approached a few minutes after returning to the pits after just being done 5-1 in heat 15 ? These riders are putting themselves on the line every time they race, and I would imagine are pretty fired up inside after a bad race. Sometimes fans need to think whether it is a good time to approach a rider or not. Holder is not renowned for being over friendly, so common sense suggests that may have been a bad moment.
