I bet you can guess the context.

"Of course. Everyone is ignorant of nearly everything. The totality of human knowledge is too vast for any one person to learn more than a tiny fraction of it in a lifetime, and all *possible* knowledge is far greater than that. All I can do is try to learn my little sliver, and maybe if I'm lucky contribute a little more.

"But I do know *how we know what we know*, and some dude sitting in his truck making a YouTube video about how evolution is fake and vaccines are a (((globalist))) plot and global warming is a hoax because it snowed yesterday ain't it."
