A great way to be vocal about what you believe in is to get some shirts printed.
I saw some people I follow got Steemit and Dtube shirts printed and I think that is awesome.
I got this vegan shirt printed in Thailand for like a few dollars.
Some places charge crazy prices for really simple shirt designs, so I think the best option is to get any design you like online and have it printed yourself.
