Worth noting that as far as I can tell, only the first one is from a group calling itself antifascist, and the triangle is a different orientation.

The cafepress link (the only one that really looks like a downward red triangle) is 2 days old.

One of the redbubble links is not even indexed yet in my google search and the other is not a red triangle, but a flag in a triangle.

society6, Redbubble & cafepress are not really primary sources of information here (and the "an" in "ancap" is short for anarchist, not antifascist).

The other link don't even feature an "upside down triangle" design, and is from Utrecht, which has a red triangle in its own flag. There's not really a connection.

Yes, it is true. I only have the time to refute one of these "examples" but:

Nobody actually involved with an Antifa group is selling Antifa-themed cafepress merchandise. The idea is laughable.

"MartStore", the vendor in question, sells a variety of politically themed merchandise, including "thin blue line" and "Trump 2020" designs. https://www.cafepress.com/profile/martstore

In western europe, this is a communist symbol more than anything, to make people remember that they were the one resisting and were also dying in concentration camps. Some communists anfa groups are indeed using it, but as a small badge.

the first link is referencing this, the second is not triangle but red/black flags, the third one is laughable, don't know about the fourth one and the last one is the anarchist flag.
