Proliferation of whining liberals occurs several times a year. To speed up their moult, all you have to do is put a MAGA cap or a Tea Party sign under their nose. Symptoms of the moult of whining liberals are the expression of words like "racist" "misogynist" or "anti-progressive", as well as hooting (much more strident in the SJWS subspecies) and tears. Their tears can serve as very effective anti-depressants.
