That's not what i typically think of when i think of third worldists, but yeah those are reactionary views. However i'm not sure that is sufficient to qualify an individual as a reactionary, let alone a whole ideological group. If that were the case then a lot of Marxist-Leninists would be reactionary too. People with progressive ideologies can hold reactionary views on some issues. People are complicated and such contradictions are very common.

The point i'm trying to make is that views such as the ones you described may be held by some individual third worldists, but these views are not integral or essential or a logical conclusion of the third worldist ideological outlook. Their ideological framework has ultra characteristics but not reactionary ones. At least as far as i can tell.
