I doubt many are actually ashamed to wear their cult regalia as much as they're bothered by the reactions of others.
The stereotypes surrounding MAGA, hats seem to be promoted by both sides, for different reasons, but they're definitely out there, and unlike a person's race, wearing a MAGA hat is a choice, from which people make inferences.
Showing MAGA pride amongst only other MAGA folks is one thing, but doing it in "mixed company" is another thing entirely. Things may change as the election gets nearer, on both sides, but after 1/6, in urban or suburban areas I don't see many Trump signs or bumper stickers, and not that many more even in more isolated rural areas.
I'm deliberately not talking about particular stereotypes here. I'm just noting that, as people go about their everyday lives, working, going to the grocery store, running errands, etc, whatever pride they may have or want to show, is likely often outweighed by dealing with the reactions of others.
The sporting event thing comes to mind. You may take pride in your team, but if you wear it to an away game, you're asking to be noticed and get attention. It could be a high five, friendly banter, or a beer poured over your head, but if you don't want the attention, you can easily choose not to wear the jersey.
