No, BBC 4 has no connection to, nor does it promote the ideas of the hard left.....I doubt if there is one media outlet which does.

It is much more dangerous and insidious than that I'm afraid Unregulated "liberalism".....or mad people in a crowd.

Every crime or misdemeanour, every social experiment(especially those involving children) is promoted   and we are advised not to be judgmental or to stigmatise as everything is always somebody else's fault......or society's.

This stuff is what Orwell visualised though he cloaked it in totalitarianism.    Insidious in the extreme
