Those “circles” were the mainstream Republican party at the time. Describing the American left as fascists is mainstream. “Transsexual fascists” is a little weird but it is not unusual to hear the left is associated with “transsexuals”, “gays”, “bisexuals”, “lgbtqwtf other letters” &etc. Saying the Democratic candidate is a traitor or terrorist or criminal who should go to prison was mainstream since Hillary Clinton ran in 2016.
