Am I a bad person if (as left as they come) I invest in American Private Prison contractors on the assumption that Trump will go through with his deportation scheme at least to some extent?
I think you'd be awfully surprised calling yourself "as left as they come" on here. There are some people who are so far out in left field that they come back around on the right again. Lemmy is full of anarcho-communists and people who believe that ownership of property is akin to murder.
You should read your own suggestion there bub. It merely says there are proponents and critics of the theory and that actual research on the metaphor is sparse. Sorry to get your panties in a twist.
I've seen the "tolerant left" suggest calling ICE on latinos who supported Donald Trump in order to get them or their family members deported as some sort of revenge. If that's not a fine example of horseshoe theory, I don't know what is.
