I'll also add that people can get PTSD from any bad experience. It's pointless to add trigger warnings because you'd have to add them to everything. Hit by a car? Now you need trigger warnings on anything about car accidents. Parent died from diabetes? Willy Wonka now needs a trigger warning. Victim of a robbery...
That said, in any sort of discussion people usually preface links to videos with violent and disturbing content with some sort of warning. If I for example, decided to drop a video of something gruesome without context I would rightfully be lambasted for doing so.
Also, your attempt at downplaying the seriousness of PTSD is really not needed. You're essentially saying that anything can cause PTSD, therefore PTSD is worthless to worry about.

> One teacher I know was recently asked by a student not to use the word “violate” in class—as in “Does this conduct violate the law?”—because the word was triggering. Some students have even suggested that rape law should not be taught because of its potential to cause distress.

> AQA’s decision to ban references of suicide from textbooks has been met with criticism from the sociology community. Anaïs Duong-Pedica argues it is naïve to assume that young people will never have encountered the idea of suicide prior to their A-levels. Refusing to engage with suicide in the classroom also marginalises students’ own experiences of suicide. Rather, measures should be put in place with and for students to accommodate the teaching and learning of sensitive topics such as suicide.

I completely agree with this use of trigger warnings, if they're given in enough time for students to actually do anything with it.
But even then, a better option would be for the person to get treatment for their PTSD, and not engage in anxiety driven safety behaviours which usually make the problem worse not better, even if they feel comforting in the short term.
And there's really no need to politicize this. It adds nothing to the conversation and only served to alienate people who might otherwise consider what you say seriously.
As to their effectiveness, unless everything has trigger warnings it’s not going to do much difference, people will still be exposed to the things that traumatise them. I’m not sure that’s a bad thing, you need to get used to living in the world sooner or later.
In short, your ideas here appear to be shaped by your politics, and they simply doesn't match up to mental health best practices for effective treatment.
Also, it's gone beyond it's originally intended purposed and begun to be used with any sort of "extreme" content, e.g., horror/gore/jump scare videos etc, where it serves as an inducement to watching, not a warning against it.
But aside from these, in the original intended context, I don't really see the behavior you mention. Maybe it's the case that a small minority are the caricatured smug virtue signaler you portray, but if so you are painting their entire use with the brush of an extreme minority of an example.
Visit a depression support group forum. You'll see just about any post with suicide content with a trigger warning. Why? Because while it's a common issue among the depressed, suicide is also contagious in a way. People already at some risk are much more likely to attempt or succeed when exposed to content of that nature. It's not uncommon for there to be a slight uptick in suicides after a public figure commits suicide. The second of two suicides within a week from survivors of the Parkland shooting may very well have been influenced in this way, as might the third suicide of parent of a Sandy Hook victim that committed suicide a few days after that.
The entire point is for people with severe trauma/PTSD to elect out of watching films or material that might bring up painful memories.
