I think a bigger issue is the acceptance of logical falicies leading to arguments that are nothing more than insult wars.
I can think of several instances but one that comes to the top was a long well reasoned argument for FM on phones. The writer put a great deal of effort into it then ended it with "do you know how stupid you sound [for taking the other position]." I made the mistake of pointing this out and was met with downvotes and told it was a very reddit thing to say.
I would love to see a platform where fallacious arguments were excluded until resubmitted or at least flagged. They do not encourage reasoned discourse.
I know there is, or was. A meth head I knew used old cell phones to watch to outside of his house. I saw the app and it worked really well. The phones were all on the same wifi and had no cell service.
