Yes. Left wing communist paraphernalia has gone mainstream and things like Che Geuvara shirts used to be edgy and cool but are now associated with reddit fedora tippers.
Right-wing stuff such as Nazi/SS insignia, Confederate flags, apartheid stuff, KKK stuff are all untouched by the mainstream.
Not only does it send a message to the liberal establishment, it gains large amounts of attention and I definitely see a gap in the market for it.
