Why don't Trump's klan wear their MAGA beanies in public?

You do not live in the right location to see them. 

Personally I do not wear hats so... I did wear mine to go vote. I put my I voted sticker on it.

I unfortunately (yup, I'll say 'unfortunately') see more of them than I would ever wish. And bumper stickers on vehicles.

And most of the time, I find highly questionable-to-me other sentiments stuck on these same vehicles, sentiments that would NOT 'make America great,' let alone 'again.'

I am the Deputy fire Warden on my floor at work.  As such, I was given a red cap to wear when we have fire drills and such and in the event of a fire, I would wear it and direct people to exits.  For years, I kept it on my desk and then Trump became president and newer employees would ask me if I was a Trump supporter.  The hat now resides in the bottom drawer of my desk.
