Opinions on purely aesthetics support?

So, currently I'm not organized in any kind of way or doing any militancy work, but liked to show my support to an agrarian reform movement just by wearing a hat that i bought in a MST fair, in two days i will be attending a geek event that has no political nature in a broader sense.

what are your thoughts about it, it is a valid display, is a petty mentality and useless?
