It's not just that Project Veritas has a far-right agenda. It's that they lie, and publish heavily edited footage taking people's statements way out of context, in order to push that agenda. They single-handedly destroyed the reputation of ACORN in the USA with their deceptive techniques.

Furthermore, they conduct surreptitious recording of their interviewees, which is illegal in some places they operate (a felony in California). They need to be shut down as a criminal organization.
