Re: Not sure how this will go.
The "cheese pizza" thing is one of the weird products of conspiracy theory culture. In this case, it comes from hacked emails from the 2016 US presidential election. Russia hacked a person running a campaign of the candidate Hilary Clinton and dumped the emails online. People who didn't like the candidate started reading them, looking for evidence. They didn't find the clear emails they were looking for, though there was some stuff for somewhat sane people to complain about. The insane people weren't worried about bureaucratic details of party politics and needed something much more intense, but one of them noticed that the various members of the party did discuss both cheese and pizza on occasion. They decided that this could mean child abuse. In exactly the same way that The Register becomes very concerning if you replace words like "cloud" with "secret plot to kill innocent people hidden in this article", this made all the people in the campaign look like child abusers if you were thinking too hard with too few brain cells. The most famous result of this particular theory was that a group of people decided that a pizza restaurant at which some campaign staff would meet must be the storehouse for child abduction victims (they had concluded it must be in the basement, even though that building didn't have one), and one of them charged in firing a gun, though nobody was hit. This is not the only consequence, just the most potentially lethal one.
Why the poster to whom you replied chose to use the term is another question. If it was intended as humor, I suggest that people not do that. In addition to the communication problems we've just seen, it could cause people to misconstrue your views.
