That seems like a broad stroke. Libertarianism is just a collection of different ideals, the same way socialism and capitalism are, around a few central values.

The primary tenants are the importance of civil liberties and autonomy (as opposed to authoritarianism).

Beyond that, you could be a libertarian and promote laissez faire capitalism, or you could be a libertarian and promote socialism. Saying you broadly disagree with libertarianism just confuses me: you don't agree with civil liberties and you want authoritarian government? (it's a rhetorical question)
