Yes i do agree with you, and a new brake from the forum is probably what will happen to me.
I have depression and so I am perhaps more susceptible to it than most. I don't really debate that much these days, but I hang around because I like many of the people here. I've been here nearly five years and I'm still trying to get the "balance" right between what kind of content I read and contribute.
But you're not imagining it. There is "something" that happens after you get caught up in the place which means you need to just take a step back. I think everyone gets it, but it may not be at the same time, some people more than others and it may affect them differently. If you tend to be very emotionally out-going and expressive, you may get hit more than someone who is a very rationalistic and analytic person who are more detached maybe.
Although tolerance is an ideal for many people, putting certain individuals on ignore is often a good idea. You do have the opportunity to "show ignored content", so you can read it occasionally and change your mind.
Alternatively, if in doubt, report it and let the staff decide if it should stay up. If it makes you
really uncomfortable, chances are it will make other people feel that way too. Otherwise you can use Site Feedback to tell the staff if you have a more specific issue you need them to look in to.
Honestly, it's all part of learning to live with the new technology. We're all still learning the basics on how much of our lives should be governed by the internet and what people say on social media. So that much we all share in common.
