In the chart of trends in how people meet, there is a suspicious uptick in "at a restaurant/bar" in the last few years... that is totally just a cover for people who met on Tinder and then got serious.
Oh? Can you point me to an instance of that usage, where "stigmata" is used as a plural of "stigma" (meaning: a socially-ostracizing feature or trait), in a contemporary, edited publication?
A will grant that it's sometimes used in the medical literature to mean "a clear, diagnostic sign of some illness", but the allusion there is to the stigmata of Christianity.
I've never, ever seen it used to mean the plural of stigma as the word is commonly used in English.
(If only because I want to avoid the "tinwhat?" discussion.)
