Man kills three, injures fourth, in workplace rampage

True liberalism and party politics are not very compatible. IMO, much of what still tries to pass as a "progressive" movement has devolved into an odd ideological cult of true believers.

"Ideologies are known for their scientific character: they combine the
scientific approach with results of philosophical relevance and pretend to be
scientific philosophy. The word "ideology" seems to imply that an idea
can become the subject matter of a science just as animals are the subject
matter of zoology, and that the suffix -logy in ideology, as in zoology, indicates
nothing but the logoi, the scientific statements made on it. If this were
true, an ideology would indeed be a pseudo-science and a pseudo-philosophy,
transgressing at the same time the limitations of science and the
limitations of philosophy. Deism, for example, would then be the ideology
which treats the idea of God, with which philosophy is concerned, in the
scientific manner of theology for which God is a revealed reality. (A theology
which is not based on revelation as a given reality but treats God as an
idea would be as mad as a zoology which is no longer sure of the physical,
tangible existence of animals.) Yet we know that this is only part of the
truth. Deism, though it denies divine revelation, does not simply make
"scientific" statements on a God which is only an "idea," but uses the idea of
God in order to explain the course of the world. The "ideas" of isms — race
in racism, God in deism, etc. — never form the subject matter of the ideologies
and the suffix -logy never indicates simply a body of "scientific" statements."
