No, liberals support freedom from (and of) religion. That doesn't mean we support all the practices of all religions. It's the conservatives who are effectively supporting Islam by wanting to set up theocracies, which will inevitably become Islamic states when Islam becomes the dominant religion, as it is on pace to become. (Atheism is growing faster, but starting from a much lower base.) Liberals want secular states, so that no religion can impose its views on anyone else.
