Basically, some white people and some men feel they are being discriminated against for supporting tRUMP. They won the election but do not feel like winners. Maybe SWS would explain it even better (Sore Winner Syndrome).
Lets face it bullies have low self esteem and thin skins.
Winning the electoral college when many did not vote at all was not much of a majority. I would guesstimate maybe 1/4 of tRUMP supporters were bigots or misogynists, 1/4 were GOP, and the other 1/2 just ill informed and believed propaganda, lies, and fake news.
