Trigger Warning

When it comes to freedom of speech and the first amendment, it seems as if we must explain what we will be talking about before we actually talk about it on the internet. Before anything graphic we label our articles with the letters TW to warn viewers of the content that may be lurking within to stir up a flashback or throw somebody into a disociative state. Do we say trigger warning before we speak out loud? Do we really need to prolong a conversation by depleting the point of it before speaking our mind over it? I am all about mental health and i will advocate for it until the day I die but if we are going to be this sensitive to what we are looking at on the internet, shouldnt we just avoid the internet? Thoughts on the trigger warning?
