Comparing trauma

Everyone knows comparing trauma, no matter to what degree, is wrong, right? But I don't think people realize that the same logic is applied to people who tries to purposely one-up someones trauma or uses their experience as a way to discredit theirs or to say how they been through much "worst". Specifically those who take any and every opportunity to talk about themselves and end up completely changing the subject at any point of someone venting in person, those who somehow thinks its fine to say " (event in person's life) is nothing compared to (event in their life) ", and ofc those who feel the need to say " Well atleast you ___". If you find yourself doing this at all, just stop. I can garentee your not helping them in anyway like this. There's nothing wrong with people venting eachother. As long as each person have their own space and opportunity to speak and express themselves, I actually find it rlly comforting. But when you find yourself making comments like this during someone else's vent and then proceed to vent yourself, you are now TRAUMA DUMPING. All trauma ,no matter the type or degree, is valid. you should NEVER veiw your trauma as superior to someone elses under any circumstances. The entire purpose of venting is to feel HEARD. They want SUPPORT. And people will legit hear people venting and be like "Oh but that's nothing compared to what I went through!". IT'S NOT SUPPOSED TO BE!!! IT’S TRAUMA!! How is that so hard for people to understand???
