Translation of AIDS quote
The original quote about AIDS is « Les sidaïques, en respirant du virus par tous les pores, mettent en cause l'équilibre de la nation. (…) Le sidaïque, – si vous voulez, j'emploie ce mot-là, c'est un néologisme, il est pas très beau mais je n'en connais pas d'autre –, celui-là, il faut bien le dire, est contagieux par sa transpiration, ses larmes, sa salive, son contact. C'est une espèce de lépreux, si vous voulez ». As a bilingual speaker, my translation would be more like:

"The aids-ers, by breathing virus from every pore, put in question the balance of the nation(...). The aids-er - if you like, I use that word, it's a neologism (coining/solecism), it's not very pretty but I don't know any other-, that [person], it must be said, is contagious through his sweat, his tears, his saliva, his touch. He's somewhat like a leper, if you like."

He does not claim that it's a type of leprosy - 'c'est une espèce de lépreux' does literally mean '(he/she/it) is a type of leper' but is in fact a colloquial way of making an imprecise comparative. So, to summarise: he makes inaccurate statements about the means of transmission of HIV, and he compares people living with HIV to lepers/leper colonies as part of his advocacy for their forced internment.
