In the US the trot to neocon pipeline is real, they really btfo of AES as well as the global south in general and they tend to be used to either purposely or by disagreement wedge labor movements at home and the La Rouchites are just weird opportunists plain and simple. To their credit there's a lot of interesting Marxist academic esp economic takes from Trots, like out of Hudson for instance. They're also sometimes good for journalist type things, when I was in college we worked with some boring newspaper Trots to break a news story about corruption.

Ideal would be to not scare everyone immediately off, just refute the ideas not the person, though with the history of Trots in the US and this being an educated by meme and meme in place of theory forum, there's only so much to be expected since you don't want to open the door to trouble neither since its a lot easier to sway discourse in an echo chamber online than it is irl as just some rando.
