'Trump supporter' is an alphabet/clown-push term, just like 'conspiracy theory'.
Can you imagine these headlines:
"Obama supporter interrupts Broadway play"
"I would never sleep with a Romney supporter"
"Bush supporter films himself shooting a deer"
"Talking sense to a Carter supporter"
"4chan Clinton supporters hack poll vote"
"5 arrested as Obama supporters clash with protesters"
(all these are actual 'trump supporter' headlines)
