There is a distinctly Randroid branch of the Republican party, who follows Alisa Zinov’yevna Rosenbaum’s (Ayn Rand) philosophy of Objectivism, and as such, see activities like giving candies to trick or treaters as actually being evil, because any sort of activity which benefits the community is evil.

To their mind, the only good is self interest, hence the title of the only Ayn Rand book that I have ever read, The Virtue of Selfishness, which I found juvenile, as well as horribly written,^* when I reviewed it as an extra credit assignment in my Philosophy of Literature class in high school.

It must be remembered that a significant portion of Republicans are actually philosophically opposed to the very idea of community.

H/t Cthulhu^† for the cartoon.

^*Seriously, really badly written. It was worse than reading Immanuel Kant, and that sh%$ was painful to read.
^†No, not the unspeakably malevolent super-being, the contributor to the Shortskoolbus BBS.^‡
‡OK, I’ve never seen the two of them together, so Cthulhu might actually be the Cthulhu, but the mere fact that he is on a BBS, interacting with humans^§ would seem to mitigate against this.
^§Yes, I know, this is the internet, where no one knows if you are a dog.
