Have I been brainwashed to believe that identity politics is a bad thing?
Can you brainwash me in the other direction?
Well... even the way you use the term "Identity Politics" is pejorative. There is nothing inherently negative about identity politics, in point of fact it is important to protect against oppression. Would you say that 1st wave feminism is intrinsically negative and that women do not have a right to vote? In the day of the suffragettes that was the identity politics of the day.
It's also wildly melodramatic to cast pronoun usage as identity politics, that's a trick the right uses to trivialise important issues pertaining to liberalism and progressive political views. But even so: who does it harm if a person is called "him" or "they" it's just such a tiny courtesy - it's hard to fathom how it could have become so contentious... util you recognise the rights need for boogeymen, then it all falls into place.
Look, let's put all this ugliness aside and employ the universal language of mathematics, this is just for you - I'm not even going to check your work.
If you truly believe that you are a Centrist then make two columns, A and B.
In A put all the times you have decried the left, used the word "leftist" pejoratively and had a fit over pronouns.
In B put down all the times you have even so much as questioned right wing media.
...if those columns are of equal length you may well be a true centrist, if they are not then you can see which side you lean to. Judging by your posts in this forum and your sources it's going to be pretty heavily right leaning I'm willing to bet.
