Congress could easily legislate the clarification to Section 230 to differentiate between "illegal content" editing and content editing. The safe-harbor would maintain when the only content removed is illegal stuff like child porn, incitement to commit felonious acts, and the like. Editing for political position would clearly be defined as "content editing" which would trigger a determination that the site is a publication, and not a message conduit.
But will the Democrats allow that distinction?
