Yeah, because streams with stated viewpoints can and ought to engage in content control, or they will be derailed.
Can't remember what meme that was about, but over a period of 6+ months I've developed a pretty good sense as to what sort of content will "trigger" conservatives. I don't actively set about to do it, but nor do I self-censor.
Indeed, any meme I submit to politics typically gets 20-30+ comments and hardly any upvotes. If that's not a good gauge of "triggered," I don't know what is.
But I've since stopped posting to politics, since it inevitably triggers debates that suck up too much of my time.
