In general that seems like a good idea, however:
There are a lot of ideas in the world, most of them are wrong, once I've identified that they are wrong, I don't care very much why or how they are wrong. I strongly suspect that if it had been Hitler whose logic I'd denied (as I certainly would), we wouldn't be having this discussion.In theory there is no difference between theory and practice, in practice there is.
The thing about Marxists so far as I am concerned isn't that they believe one arbitrary wrong thing, it's that they believe a whole conjoined mess of wrong things, as do fascists, and a bunch of other groups, the particulars of which cannot be discussed here.
So, Amber's grabbed and disarmed him, apparently. I wonder what's next.
