Aketon, you ask how can people espouse socialism when there are
those on the left who send their children to private schools?
First of all not socialists do this. Second, many are thought to be
socialists when in fact they are branded by right wingers as such.

Socialism is a economic and political philosophy and like any
other ideological construct, there are different ways to interpret
it. You are looking for consistency in an all too human world which
is tilting at windmills. Many of the principles are workable
applied to politics and economics regardless of the practioners and their embracing or rejecting of some parts or all of it.

You might as well say that any form of ideology is invalid when
compromised by any who say they follow it. So in that logic,
all religion, political parties, philosophical thought has to be invalid because someone doesn't follow it to the letter.

Socialism is also a large tent and there are many warring tribes that live beneath it. It's rare to find socialists that agree conclusively about everything. It's not a lock-step sheep herded type of thing but requires a lot of thinking and rehashing to
define it.
