You could translate it as "how dare you trying to sabotage my career by attacking my research", something like this. It is fairly common that researchers build their careers on single results/breakthroughs and those have to be fiercely defended against everyone. For example, by rejecting/delaying research grants/papers that are competing with your own opinion/results, thanks to anonymous peer review. Sounds crazy, but I have seen this more than once.
