Back in the days when Lefties thought that the Environment explained human behaviour (1970's) and never conceived that genetics would one day revolutionize human understanding of this naive politicized view we never considered we would now have not only " 'isms" but also, " 'obias".
In days past, we had: Socialism, Communism, Trotskyism, Internationalism, Stalinism, Racism, Leftism, Liberalism, Nazism, etc etc.
Now we also have: homophobia, xenophobia, Islamaphobia, commitmentphobia, arachnophobia etc etc.
So what has happened and why has the suffix changed?
Does this suffix change mean an end to (usually lefty liberal) ideology and the beginning of (usually lefty liberal) personal abuse?
In other words, a change of tactic. Instead of changing the world through a process of ideology they now want to insult you and change your mind at the same time.
Personally, I think the suffix change reveals exactly this. Most people in Britain were unaware, until the past few years, that they had been discriminating against anyone in particular. Now, or so it appears, we are all criminals. Now we are all, xenophobic, homophobic, Islamaphobic etc etc.
Have we not heard all this before?
And, are we not, we English, the most tolerant people on the planet to take this abuse day in, day out? It appears that the "isms" have now evolved into "obias".
Good luck all and, as Dave Allen may once have said, "may your (politically correct) God go with you".
