At the very least it is not plausible at all that the trump campaign intentionally and openly uses Nazi iconography to mark them as to be gassed, using an additional 88 (=...) symbol in tandem. That is not plausible. In particular because of the source.
In a day or two this will be officially proven to be a complete lie, but no one will care. And submissions to document this will be ignored like they always are.
Every single instance of an upside down red triangle on an image search for "antifa symbol" is a screenshot of a post from the Trump campaign. There is no use of the symbol without referring to that campaign post.
Like that time he had an image of Hillary Clinton, on a background of money, with a "most corrupt ever" caption written in the middle of a star of David. It's intentional.
Frankly, the narrative that he's anti-Semitic is not credible considering his "favorite" daughter converted to Christianity with his support.
You're probably confused because like a normal person you see a contradiction, and you appear to resolve it with the most charitable interpretation. Others may resolve it with the non charitable explanation.
He on the other hand has no problem with the contradiction of using an anti-semitic ad while having Jewish family if the ad resonates with his supporters and serves his interests, which it did.
This is one of his unique abilities: allegiance to nothing but himself, therefore contradictions that arise from loyalty to a principle or person are meaningless.
I don't think the concentration camp symbol is very plausible either since no one has seen that symbol since 1945.
Can you point to any white supremacist posts or site that use it?
