Question about counter protests.

So I am a young angry white male. I am angry at the scores of ignorant white men that try to speak for me and other white people. They're wrong and their rhetoric has no place in this country. With that being said.... I kinda look like a nazi. I have to look clean cut and we'll dressed for work. I have been seen as a supporter of the alt right at protests before even though I am staunchly supposed to everything they believe in. What can I do or wear to differentiate myself from them? I plan on attending a counter protest in Berkeley later this month and I don't want there to be a question of where my allegiances lay. I thought about carrying a rainbow flag but I don't want to flag pole itself to be seen as a weapon. Any suggestions would be great. Thanks
