This is a pretty normal route of radicalization. Libertarian socialism definitely jives more with the propaganda that Americans grew up with. My path was libertarian -> Bernie lib / socdem -> anarchist -> Marxist / ml. What got me was basically reading about the success rates of anarchism vs MLism, honestly I still feel like anarchism/libsoc aligns with my ideals more than MLism. But unfortunately it just can't really defend itself like ML revolutions can
