Casual use of "Boomer" (or other dismissive term), to divide our large older voting base with our younger voters, or other targeted group. The left regularly uses one or two word attacks to "sum up" someone in order to demonize, dismiss, or convince others to dismiss their question and opinions. https://www.logicalfallacies.org/ad-hominem.html

Ridicule of some other conservative subgroup, trying to sew division between us. Anything they can use to try to make some of our user base stop viewing the site or feel alienated. Usually appears as a "flavor of the week" stigma, which are replaced as soon as it's convenient.

Blame or casually targeting a religion or race as if it's normal. These are usually created by democrat shills who create fake posts to report for content, trying to get us shut down. These also sometimes tie in some random race/religion blame with some important view we'd normally have, attempting to cobble together some tenuous relationship that doesn't exist.

These are three that I've seen pretty prominently recently. Feel free to add more as comments.
