A wing of a terrorist party
It leads through a maze of "Non-profit" and "Non-Government-Organizations", many of which are funded by Federal and State grants. That is where ties to the Democrat party enter the picture. There are also several rings of Private Foundations which are funded by families of the billionaires' clubs.
ANTIFA is a very decentralized operation, but hardly "leaderless". They have access to a great deal of money and their leaders are full-time professionals with considerable training. It is basically a franchise operation, descended from original Communist front groups in Germany.
They are very good at recruiting disaffected young people and mobilizing them for hostile or violent "protests". But they only flourish in areas where the local authorities tolerate them. Presumably that is because they are careful to select only "approved" targets.
Looks like San Diego might not be quite as tolerant as they expected.
