You obviously have your own bias if you encounter it multiple times daily. That isn't average.
I don't know what you mean by "the media" but I'd like to see a clearer description. I'm not talking about what I see in the news or on tv shows and movies, I'm talking about what I see in real life and occasionally places like facebook or something.
And it isn't just the proud boys tarnishing it. I saw it used by a lot of antivaxxers during the height of the pandemic side by side with their science denial and misinformation, as another example.
the "true meaning" of things like symbols is always opinion. you seem to be arguing, for the sake of the gadsden flag, that symbols only ever mean what they were originally intended to mean, and that just isn't the case.
In my opinion, the gadsden flag belongs in the past. Hateful modern use of the flag has tainted and ruined any positive association it could have brought. Now it means antisemitism, homophobia and transphobia, sexism, political extremism, anti-intellectualism, and more, a symbol of the values of the people who use it most often.
