And why would they need to put Castro's son on the throne? And who are they? It's trivial to get a DNA sample these days. How about a full genomic sample from Trudeau? And even if he was Castro's son, so?

Jim Morrison's father was Gulf of Tonkin False Flag asset Navy scumbag, but somehow Jim Morrison didn't turn out to be like his father (just screwed up differently).

I like associations as well, and I'm no lover of Trudeau, but the jump "Trudeau if Castro's illegitimate son" -> "Cabal placed Trudeau on the throne to make Canada a slave Communist state" is stretching it without further proof.
