Until one learns to disregard untrue statements, one is going to be puppeteered by them.
Considering your use of euphemisms for white supremacy, such as "white advocacy," it sounds like people dismiss you as a Nazi because you are factually a Nazi. I encourage you to find the courage to advocate for your beliefs on your main account instead of registering throwaways to avoid negative consequences for your choices.
