If you're asking what the SPLC is, even if you google it and see the first result, you have no skin in this game. Sit this discussion out. You're just using this opportunity to leak your anti-semitism and you're not even being subtle about it.

Maybe just explain what it is instead of avoiding my point?

Those who defend Israeli colonialism actually increase anti-semitism in the world and no amount of intentional conflation of Judaism and Zionism will erase that. Maybe you'll realize that one day.
